RTS eventlog events for postCapsetVecEvent are truncated if payload
is larger than EVENT_PAYLOAD_SIZE_MAX
Previously, postCapsetVecEvent records eventlog event with payload
of variable size larger than EVENT_PAYLOAD_SIZE_MAX (2^16) without
any validation, resulting in corrupted data.
For example, this happens when a Haskell binary is invoked with very
long command line arguments exceeding 2^16 bytes (see #20221).
Now we check the size of accumulated payload messages incrementally,
and truncate the message just before the payload size exceeds
EVENT_PAYLOAD_SIZE_MAX. RTS will warn the user with a message showing
how many arguments are truncated.

Hadrian used to pass -g when building all ways of rts. It makes output
binaries larger (especially so for wasm backend), and isn't needed by
most users out there, so this patch removes that flag. In case the
debug info is desired, we still pass -g3 when building the debug way,
and there's also the debug_info flavour transformer which ensures -g3
is passed for all rts ways.

The Show instance for TypeRep [] has changed in 9.5 to output "List"
because the name of the type constructor changed.
This seems to be accidental and is inconsistent with TypeReps of saturated
lists, which are printed as e.g. "[Int]".
For now, I'm restoring the old behavior; in the future,
maybe we should show TypeReps without puns (List, Tuple, Type).

In this job we can run on every commit we add a test which builds the
Cabal library twice and checks that the ABI hash and interface hash is
stable across the two builds.
* We run the test 20 times to try to weed out any race conditions due to
`-j`
* We run the builds in different temporary directories to try to weed
out anything related to build directory affecting ABI or interface
file hash.

The idea is that both the bindists should product libraries with the
same ABI and interface hash.
So the job checks with ghc-pkg to make sure the computed ABI
is the same.
In future this job can be extended to check for the other facets of
interface determinism.

There was some code in the signature merging logic which added together
the ImportAvails of the signature and the signature which was merged
into it. This had the side-effect of making the merged signature depend
on the signature (via a normal module dependency). The intention was to
propagate orphan instances through the merge but this also messed up
recompilation logic because we shouldn't be attempting to load B.hi when
mergeing it.
The fix is to just combine the part of ImportAvails that we intended to
(transitive info, orphan instances and type family instances) rather
than the whole thing.

In #22217 it was observed that the order modules are compiled in affects
the contents of an interface file. This was because a module dependended
on another module indirectly, via a re-export but the interface file for
this module was never loaded because the symbol was never used in the
file.
If we decide that we depend on a module then we jolly well ought to
record this fact in the interface file! Otherwise it could lead to very
subtle recompilation bugs if the dependency is not tracked and the
module is updated.
Therefore the best thing to do is just to make sure the file is loaded
by calling the `loadSysInterface` function. This first checks the
caches (like we did before) but then actually goes to find the interface
on disk if it wasn't loaded.
Fixes #22217

So that we get to cancel away the allocation for the lazily used base.
We can move `powImpl` (which *is* strict in the base) to the top-level
so that we don't duplicate too much code and move the SPECIALISATION
pragmas onto `powImpl`.
The net effect of this change is that `(^)` plays along much better with
inlining thresholds and loopification (#22227), for example in `x2n1`.

There was some confusion in Data.Typeable about which module certain

doesn't mean it comes from GHC.Prim, in particular things like LiftedRep
and RuntimeRep are defined in GHC.Types and that's the end of the story.
Things like Int#, Float# etc are defined in GHC.Prim as they have no
Haskell definition site at all so we need to generate type

As discovered in #22272, dehydration of the unfolding info of a
recursive definition used to involve a traversal of the definition
itself, which in turn involves traversing the unfolding info. Hence,
a loop.
Instead, we now store enough data in the interface that we can produce
the unfolding info without this traversal. See Note [Tying the 'CoreUnfolding' knot]
for details.

The Lint check for branch compatiblity within an axiom, in

check made when contructing an axiom, in
GHC.Core.FamInstEnv.compatibleBranches.
The latter is correct, so I killed the former and am now using the
latter.

Previously, the `checkValidInst` function (used when checking that an instance
declaration is headed by an actual type class, not a type synonym) was using
`tcSplitSigmaTy` to split apart the `forall`s and instance context. This is
incorrect, however, as `tcSplitSigmaTy` expands type synonyms, which can cause
instances headed by quantified constraint type synonyms to be accepted
erroneously.
This patch introduces `splitInstTyForValidity`, a variant of `tcSplitSigmaTy`
specialized for validity checking that does _not_ expand type synonyms, and
uses it in `checkValidInst`.
Fixes #22570.

without knowing its function signature, we used to fallback to `() ->
()` which is accepted by `wasm-ld`. This patch changes it to the
signature of Cmm functions, which equally works, but would be required
when we emit tail call instructions.

When the `-mtail-call` clang flag is passed at configure time, wasm
tail-call extension is enabled, and the wasm NCG will emit
`return_call`/`return_call_indirect` instructions to take advantage of
it and avoid the `StgRun` trampoline overhead.
Closes #22461.

Fix #22459, in two ways:
(1) Make the Specialiser not create a bogus specialisation if
it is presented by strangely polymorphic dictionary.
See Note [Weird special case in SpecDict] in
GHC.Core.Opt.Specialise
(2) Be more careful in abstractFloats
See Note [Which type variables to abstract over]
in GHC.Core.Opt.Simplify.Utils.
So (2) stops creating the excessively polymorphic dictionary in
abstractFloats, while (1) stops crashing if some other pass should
nevertheless create a weirdly polymorphic dictionary.

A long time ago we would rely on substitutions from the configure script
to inject paths of the include and library directories of libffi and
libdw. However, now these are instead handled inside Hadrian when
calling Cabal's `configure` (see the uses of `cabalExtraDirs` in
Hadrian's `Settings.Packages.packageArgs`).
While the occurrences in the cabal file were redundant, they did no
harm. However, since b5c714545abc5f75a1ffdcc39b4bfdc7cd5e64b4 they have
no longer been interpolated. @mpickering noticed the suspicious
uninterpolated occurrence of `@FFIIncludeDir@` in #22595,
prompting this commit to finally remove them.

This avoids a lock inversion between the storage manager mutex and
the stable pointer table mutex by not dropping the SM_MUTEX in
nonmovingCollect. This requires quite a bit of rejiggering but it
does seem like a better strategy.

This enables the SLOW_VALIDATE env var for the linting head.hackage
jobs, namely the jobs enabled manually, by the label or on the nightly
build now use the deb10-numa-slow-validate bindist which has assertions
enabled.
See #22623 for a ticket which was found by using this configuration
already!
The head.hackage jobs triggered by upstream CI are now thusly:
hackage-lint: Can be triggered on any MR, normal validate pipeline or nightly build.
Runs head.hackage with -dlint and a slow-validate bindist
hackage-label-lint: Trigged on MRs with "user-facing" label, runs the slow-validate
head.hackage build with -dlint.
nightly-hackage-lint: Runs automatically on nightly pipelines with slow-validate + dlint config.
nightly-hackage-perf: Runs automaticaly on nightly pipelines with release build and eventlogging enabled.
release-hackage-lint: Runs automatically on release pipelines with -dlint on a release bindist.

This change allows less priviledged users to trigger head.hackage jobs
because less permissions are needed to trigger jobs on the
upstream-testing branch, which is not protected.
There is a CI job which updates upstream-testing each hour to the state
of the master branch so it should always be relatively up-to-date.

In #20472 it was pointed out that you couldn't defer out of scope but
the implementation collapsed a RdrName into an OccName to stuff it into
a Hole. This leads to the error message for a deferred qualified name
dropping the qualification which affects the quality of the error
message.
This commit adds a bit more structure to a hole, so a hole can replace a
RdrName without losing information about what that RdrName was. This is
important when printing error messages.
I also added a test which checks the Template Haskell deferral of out of
scope qualified names works properly.
