rts: fix ctoi_tuple_spill_words getting out of sync
Fix a few places that were not updating ctoi_tuple_spill_words
correctly, leading to corruption/crashes when dealing with large
unboxed tuples in bytecode:
- captureContinuationAndAbort
- findRetryFrameHelper/findAtomicallyFrameHelper
- interpretBCO bci_BRK_FUN
fixes #27633

Hadrian: don't capture the testsuite driver's output (#27780)
a6061455d54 switched the Testsuite RunTest case from Shake's cmd to the
cmd' wrapper. cmd' always captures stdout and stderr, and since the
caller asks for Exit, it returns without dumping what it captured. As a
result the testsuite output no longer appears in CI job logs: failures,
performance metrics and the summary were lost with the job.
Use cmdExe, the uncaptured cmd, as the other plain-cmd sites in that
commit do.
Fixes #27780.

rts: Fix missing memory barrier in eval_thunk_selector (#27477)
unchain_thunk_selectors() was missing an ACQUIRE_LOAD for the
indirectee, leading to segfaults and corruption during GC on
weakly-ordered architectures.

EPA Fix HsCmdDo exact print with comments
Exact printing of HsCmdDo was ignoring the location for the do
statements, and this is an annotation that can have comments in it.
Update it so we print the statements as a unit, including any
comments.
Also add the result of auditing that we capture comments in all needed
places, noting that the remaining Anno SrcSpan instances are benign.

Extend TcGblEnv with a mapping from instance method Ids to DFunIds
We want to use this in HPC to provide better support for instance methods.
This is working towards #17155.

hpc: Do not create top-level boxes for generated instance methods
Users care about which of their written methods are or aren't covered, not
whether all of the inherited methods are covered as well. Those should be
covered where they are implemented.
We achieve that by stopping to generate top-level boxes which will often appear
as uncovered with no clear indication as to why, and no way to fix other than
excercising code the user has not written.
Fixes #17155.

hpc: Provide coverage information for class instances
After fixing #17155, we no longer create top-level boxes for the source spans
of instance heads (previously that was the source span used for
inherited/generated instance methods).
With those boxes gone, we can introduce a new top-level box for each class
instance with that instance head source span, and provide more meaningful
coverage semantics for it.
We make the use of any of the instance's methods (user-written or generated)
tick this box, providing the programmer with useful information about whether
or not the instance was exercised at run-time, and whether the instance might
be unnecessary.

hpc: Don't allocate boxes for methodless classes
With the plumbing we currently have, these could never be covered, which is not
helpful to hpc users. This could be improved upon further.
