Print fully qualified unit names in name mismatch
It's more user-friendly to directly print the right thing instead of
requiring the user to retry with the additional `-dppr-debug` flag.

configure: Fix consistency between distrib and source CC check
Previously distrib/configure.ac did not
include `cc`.
Closes #26394.

Use isPrint in showUnique
The comment say
```
-- Avoid emitting non-printable characters in pretty uniques. See #25989.
```
so let the code do exactly that.
There are tags (at least : and 0 .. 9) which weren't in A .. z range.

Shorten in-module links in hyperlinked source
Instead of href="This.Module#ident" to just "#ident"

Use showUnique in internalAnchorIdent
Showing the key of Unique as a number is generally not a great idea.
GHC Unique has a tag in high bits, so the raw number is unnecessarily
big.
So now we have
```html
<a href="#l-rvgK"><span class="hs-identifier hs-var hs-var">bar</span></a>
```
instead of
```html
<a href="#local-6989586621679015689"><span class="hs-identifier hs-var hs-var">bar</span></a>
```
Together with previous changes of shorter intra-module links the effect
on compressed files is not huge, that is expected as we simply remove
repetitive contents which pack well.
```
12_694_206 Agda-2.9.0-docs-orig.tar.gz
12_566_065 Agda-2.9.0-docs.tar.gz
```
However when unpacked, the difference can be significant,
e.g. Agda's largest module source got 5% reduction:
```
14_230_117 Agda.Syntax.Parser.Parser.html
13_422_109 Agda.Syntax.Parser.Parser.html
```
The whole hyperlinked source code directory got similar reduction
```
121M Agda-2.9.0-docs-orig/src
114M Agda-2.9.0-docs/src
```
For the reference, sources are about 2/3 of the generated haddocks
```
178M Agda-2.9.0-docs-old
172M Agda-2.9.0-docs
```
so we get around 3.5% size reduction overall. Not bad for a small local
changes.

rts: Fix alignment for gen_workspace #26334
After a0fa4941903272c48b050d24e93eec819eff51bd bootstrap is broken on
s390x and errors out with
rts/sm/GCThread.h:207:5: error:
error: alignment of array elements is greater than element size
207 | gen_workspace gens[];
| ^~~~~~~~~~~~~
The alignment constraint is applied via the attribute to the type
gen_workspace and leaves the underlying type struct gen_workspace_
untouched. On Aarch64, x86, and s390x the struct has a size of 128
bytes. On Aarch64 and x86 the alignments of 128 and 64 are divisors of
the size, respectively, which is why the type is a viable member type
for an array. However, on s390x, the alignment is 256 and therefore is
not a divisor of the size and hence cannot be used for arrays.
Basically I see two fixes here. Either decrease the alignment
requirement on s390x, or by applying the alignment constraint on the
struct itself. The former might affect performance as noted in
a0fa4941903272c48b050d24e93eec819eff51bd. The latter introduces padding
bits whenever necessary in order to ensure that
sizeof(gen_workspace[N])==N*sizeof(gen_workspace) holds which is done by
this patch.

ghci: add :shell command
This patch adds a new :shell command to ghci which works similarly to
:!, except it guarantees to run the command via sh -c. On POSIX hosts
the behavior is identical to :!, but on Windows it uses the msys2
shell instead of system cmd.exe shell. This is convenient when writing
simple ghci scripts that run simple POSIX commands, and the behavior
can be expected to be coherent on both Windows and POSIX.

Enable TcM plugins in initTc
This commit ensures that we run typechecker plugins and defaulting
plugins whenever we call initTc.
In particular, this ensures that the pattern-match checker, which calls
'initTcDsForSolver' which calls 'initTc', runs with typechecker plugins
enabled. This matters for situations like:
merge :: Vec n a -> Vec n a -> Vec (2 * n) a
merge Nil Nil = Nil
merge (a <: as) (b <: bs) = a :< (b <: merge as bs)
in which we need the typechecker plugin to run in order to tell us that
the Givens would be inconsistent in the additional equation
merge (_ <: _) Nil
and thus that the equation is not needed.
Fixes #26395

Bad record update msg: allow out-of-scope datacons
This commit ensures that, when we encounter an invalid record update
(because no constructor exists which contains all of the record fields
mentioned in the record update), we graciously handle the situation in
which the constructors themselves are not in scope. In that case,
instead of looking up the constructors in the GlobalRdrEnv, directly
look up their GREInfo using the lookupGREInfo function.
Fixes #26391

Improve Notes about disambiguating record updates
This commit updates the notes [Disambiguating record updates] and
[Type-directed record disambiguation], in particular adding more
information about the deprecation status of type-directed disambiguation
of record updates.
