Refactor the treatment of nested Template Haskell splices
* The difference between a normal splice, a quasiquoter and implicit
splice caused by lifting is stored in the AST after renaming.
* Information that the renamer learns about splices is stored in the
relevant splice extension points (XUntypedSpliceExpr, XQuasiQuote).
* Normal splices and quasi quotes record the flavour of splice
(exp/pat/dec etc)
* Implicit lifting stores information about why the lift was attempted,
so if it fails, that can be reported to the user.
* After renaming, the decision taken to attempt to implicitly lift a
variable is stored in the `XXUntypedSplice` extension field in the
`HsImplicitLiftSplice` constructor.
* Since all the information is stored in the AST, in `HsUntypedSplice`,
the type of `PendingRnSplice` now just stores a `HsUntypedSplice`.
* Error messages since the original program can be easily
printed, this is noticeable in the case of implicit lifting.
* The user-written syntax is directly type-checked. Before, some
desugaring took place in the
* Fixes .hie files to work better with nested splices (nested splices
are not indexed)
* The location of the quoter in a quasiquote is now located, so error
messages will precisely point to it (and again, it is indexed by hie
files)
In the future, the typechecked AST should also retain information about
the splices and the specific desugaring being left to the desugarer.
Also, `runRnSplice` should call `tcUntypedSplice`, otherwise the
typechecking logic is duplicated (see the `QQError` and `QQTopError`
tests for a difference caused by this).

Specialise: Don't float out constraint components.
It was fairly complex to do so and it doesn't seem to improve anything.
Nofib allocations were unaffected as well.

+Function `specCase` used to give special treatment to a case-expression

g = \d. case d of { MkD sc ... -> ...(f sc)... }
-Naively we can't float d2's binding out of the case expression,
-because 'sc' is bound by the case, and that in turn means we can't
-specialise f, which seems a pity.
-
-So we invert the case, by floating out a binding
-for 'sc_flt' thus:
- sc_flt = case d of { MkD sc ... -> sc }
-Now we can float the call instance for 'f'. Indeed this is just
-what'll happen if 'sc' was originally bound with a let binding,
-but case is more efficient, and necessary with equalities. So it's
-good to work with both.
-
-You might think that this won't make any difference, because the
-call instance will only get nuked by the \d. BUT if 'g' itself is
-specialised, then transitively we should be able to specialise f.
-
-In general, given
- case e of cb { MkD sc ... -> ...(f sc)... }
-we transform to
- let cb_flt = e
- sc_flt = case cb_flt of { MkD sc ... -> sc }
- in
- case cb_flt of bg { MkD sc ... -> ....(f sc_flt)... }
-
-The "_flt" things are the floated binds; we use the current substitution
-to substitute sc -> sc_flt in the RHS
+But actually
+
+* We never explicitly case-analyse a dictionary; rather the class-op
+ rules select superclasses from it. (NB: worker/wrapper can unbox
+ tuple dictionaries -- see (DNB1) in Note [Do not unbox class dictionaries];
+ but that's only after worker/wrapper, and specialisation happens before
+ that.)
+
+* Calling `interestingDict` on every scrutinee is hardly sensible;
+ generally `interestingDict` is called only on Constraint-kinded things.

Interpreter: Add limited support for direct primop evaluation.
This commit adds support for a number of primops directly
to the interpreter. This avoids the indirection of going
through the primop wrapper for those primops speeding interpretation
of optimized code up massively.
Code involving IntSet runs about 25% faster with optimized core and these
changes. For core without breakpoints it's even more pronouced and I
saw reductions in runtime by up to 50%.
Running GHC itself in the interpreter was sped up by ~15% through this
change.
Additionally this comment does a few other related changes:
testsuite:
* Run foundation test in ghci and ghci-opt ways to test these
primops.
* Vastly expand the foundation test to cover all basic primops
by comparing result with the result of calling the wrapper.
Interpreter:
* When pushing arguments for interpreted primops extend each argument to
at least word with when pushing. This avoids some issues with big
endian. We can revisit this if it causes performance issues.
* Restructure the stack chunk check logic. There are now macros for
read accesses which might cross stack chunk boundries and macros which
omit the checks which are used when we statically know we access an
address in the current stack chunk.

Track rewriter sets more accurately in constraint solving
This MR addresses #26003, by refactoring the arcane
intricacies of Note [Equalities with incompatible kinds].
NB: now retitled to
Note [Equalities with heterogeneous kinds].
and the main Note for this MR.
In particular:
* Abandon invariant (COERCION-HOLE) in Note [Unification preconditions] in
GHC.Tc.Utils.Unify.
* Abandon invariant (TyEq:CH)) in Note [Canonical equalities] in
GHC.Tc.Types.Constraint.
* Instead: add invariant (REWRITERS) to Note [Unification preconditions]:
unify only if the constraint has an empty rewriter set.
Implementation:
* In canEqCanLHSFinish_try_unification, skip trying unification if there is a
non-empty rewriter set.
* To do this, make sure the rewriter set is zonked; do so in selectNextWorkItem,
which also deals with prioritisation.
* When a coercion hole is filled, kick out inert equalities that have that hole
as a rewriter. It might now be unlocked and available to unify.
* Remove the ad-hoc `ch_hetero_kind` field of `CoercionHole`.
* In `selectNextWorkItem`, priorities equalities withan empty rewriter set.
* Defaulting: see (DE6) in Note [Defaulting equalities]
and Note [Limited defaulting in the ambiguity check]
* Concreteness checks: there is some extra faff to try to get decent
error messages when the FRR (representation-polymorphism) checks
fail. In partiular, add a "When unifying..." explanation when the
representation-polymorphism check arose from another constraint.

compiler: Clarify BCO size
Previously the semantics and size of StgBCO was a bit unclear.
Specifically, the `size` field was documented to contain the size of the
bitmap whereas it was actually the size of the closure *and* bitmap.
Additionally, it was not as clear as it could be that the bitmap was a
full StgLargeBitmap with its own `size` field.

debugger: Toggle step-in per thread, not globally
The RTS global flag `rts_stop_next_breakpoint` used to tell the
interpreter to stop at the immediate next breakpoint.
Now, this flag is definited per thread in the TSO flag (TSO_STOP_NEXT_BREAKPOINT).
Being able to toggle "stop at next breakpoint" per thread is an
important requirement for implementing "stepping out" of a function in a
multi-threaded context.
More generally, having a per-thread flag for single-stepping paves the
way for multi-threaded debugging.
That said, when we want to enable "single step" mode for the whole
interpreted program we still want to stop at the immediate next
breakpoint, whichever thread it belongs to.
Therefore, use `rts_enableStopNextBreakpointAll` and
`rts_disableStopNextBreakpointAll` for the exisiting single-step
commands.
Preparation for #26042

Specialse: Specialise on Dictionaries with Opaque types.
Surfaced by #19747 I realized that sometimes we end up with types
like `SomeTyFam Foo` which represent a concrete deterministic
dictionary but in the specializer we can't infer this just from the
Type.
So when deciding if a dictionary should be specialized on we now look
at the argument term *and* types. `Note [Interesting dictionary arguments]`
has all the details.

Note [Interesting dictionary arguments]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-In `mkCallUDs` we only use `SpecDict` for dictionaries of which
-`interestingDict` holds. Otherwise we use `UnspecArg`. Two reasons:
-
-* Consider this
- \a.\d:Eq a. let f = ... in ...(f d)...
- There really is not much point in specialising f wrt the dictionary d,
- because the code for the specialised f is not improved at all, because
- d is lambda-bound. We simply get junk specialisations.
-
-* Consider this (#25703):
- f :: (Eq a, Show b) => a -> b -> INt
- goo :: forall x. (Eq x) => x -> blah
- goo @x (d:Eq x) (arg:x) = ...(f @x @Int d $fShowInt)...
- If we built a `ci_key` with a (SpecDict d) for `d`, we would end up
- discarding the call at the `\d`. But if we use `UnspecArg` for that
- uninteresting `d`, we'll get a `ci_key` of
- f @x @Int UnspecArg (SpecDict $fShowInt)
- and /that/ can float out to f's definition and specialise nicely.
- Hooray. (NB: the call can float only if `-fpolymorphic-specialisation`
- is on; otherwise it'll be trapped by the `\@x -> ...`.)(
-
-What is "interesting"? (See `interestingDict`.) Just that it has *some*
-structure. But what about variables? We look in the variable's /unfolding/.
-And that means that we must be careful to ensure that dictionaries /have/

-* cloneBndrSM discards non-Stable unfoldings
-* specBind updates the unfolding after specialisation
- See Note [Update unfolding after specialisation]
-* bindAuxiliaryDict adds an unfolding for an aux dict
- see Note [Specialisation modulo dictionary selectors]
-* specCase adds unfoldings for the new bindings it creates

+Consider this
+ \a.\d:Eq a. let f = ... in ...(f d)...
+There really is not much point in specialising f wrt the dictionary d,
+because the code for the specialised f is not improved at all, because
+d is lambda-bound. We simply get junk specialisations.
+
+What is "interesting"? Our Main Plan is to use `exprIsConApp_maybe` to see
+if the argument is a dictionary constructor applied to some arguments, in which
+case we can clearly specialise. But there are wrinkles:
+
+(ID1) Note that we look at the argument /term/, not its /type/. Suppose the
+ argument is
+ (% d1, d2 %) |> co
+ where co :: (% Eq [a], Show [a] %) ~ F Int a, and `F` is a type family.
+ Then its type (F Int a) looks very un-informative, but the term is super
+ helpful. See #19747 (where missing this point caused a 70x slow down)
+ and #7785.
+
+(ID2) Note that the Main Plan works fine for an argument that is a DFun call,
+ e.g. $fOrdList $dOrdInt
+ because `exprIsConApp_maybe` cleverly deals with DFunId applications. Good!
+
+(ID3) For variables, we look in the variable's /unfolding/. And that means
+ that we must be careful to ensure that dictionaries /have/ unfoldings:
+ * cloneBndrSM discards non-Stable unfoldings
+ * specBind updates the unfolding after specialisation
+ See Note [Update unfolding after specialisation]
+ * bindAuxiliaryDict adds an unfolding for an aux dict
+ see Note [Specialisation modulo dictionary selectors]
+ * specCase adds unfoldings for the new bindings it creates
+
+ We accidentally lost accurate tracking of local variables for a long
+ time, because cloned variables didn't have unfoldings. But makes a
+ massive difference in a few cases, eg #5113. For nofib as a
+ whole it's only a small win: 2.2% improvement in allocation for ansi,
+ 1.2% for bspt, but mostly 0.0! Average 0.1% increase in binary size.
+
+(ID4) We must be very careful not to specialise on a "dictionary" that is, or contains
+ an implicit parameter, because implicit parameters are emphatically not singleton
+ types. See #25999:
+ useImplicit :: (?i :: Int) => Int
+ useImplicit = ?i + 1
+
+ foo = let ?i = 1 in (useImplicit, let ?i = 2 in useImplicit)
+ Both calls to `useImplicit` are at type `?i::Int`, but they pass different values.
+ We must not specialise on implicit parameters! Hence the call to `couldBeIPLike`.
+
+(ID5) Suppose the argument is (e |> co). Can we rely on `exprIsConApp_maybe` to deal
+ with the coercion. No! That only works if (co :: C t1 ~ C t2) with the same type
+ constructor at the top of both sides. But see the example in (ID1), where that
+ is not true. For thes same reason, we can't rely on `exprIsConApp_maybe` to look
+ through unfoldings (because there might be a cast inside), hence dealing with
+ expandable unfoldings in `interestingDict` directly.
+
+(ID6) The Main Plan says that it's worth specialising if the argument is an application
+ of a dictionary contructor. But what if the dictionary has no methods? Then we
+ gain nothing by specialising, unless the /superclasses/ are interesting. A case
+ in point is constraint tuples (% d1, .., dn %); a constraint N-tuple is a class
+ with N superclasses and no methods.
+
+(ID7) A unary (single-method) class is currently represented by (meth |> co). We
+ will unwrap the cast (see (ID5)) and then want to reply "yes" if the method
+ has any struture. We rather arbitrarily use `exprIsHNF` for this. (We plan a
+ new story for unary classes, see #23109, and this special case will become
+ irrelevant.)
+
+(ID8) Sadly, if `exprIsConApp_maybe` says Nothing, we still want to treat a
+ non-trivial argument as interesting. In T19695 we have this:
+ askParams :: Monad m => blah
+ mhelper :: MonadIO m => blah
+ mhelper (d:MonadIO m) = ...(askParams @m ($p1 d))....
+ where `$p1` is the superclass selector for `MonadIO`. Now, if `mhelper` is
+ specialised at `Handler` we'll get this call in the specialised `$smhelper`:
+ askParams @Handler ($p1 $fMonadIOHandler)
+ and we /definitely/ want to specialise that, even though the argument isn't
+ visibly a dictionary application. In fact the specialiser fires the superclass
+ selector rule (see Note [Fire rules in the specialiser]), so we get
+ askParams @Handler ($cp1MonadIO $fMonadIOIO)
+ but it /still/ doesn't look like a dictionary application.
+
+ Conclusion: we optimistically assume that any non-trivial argument is worth
+ specialising on.
+
+ So why do the `exprIsConApp_maybe` and `Cast` stuff? Because we want to look
+ under type-family casts (ID1) and constraint tuples (ID6).
