Bump transformers submodule
The svg image files mentioned in transformers.cabal were
previously not checked in, which broke sdist generation.

Repair the 'build-cabal' hadrian target
Fixes #23117. Fixes #23281. Fixes #23490.
This required:
* Updating the bit-rotted compiler/Setup.hs and its setup-depends
* Listing a few recently-added libraries and utilities
in cabal.project-reinstall
* Setting allow-boot-library-installs to 'True' since Cabal
now considers the 'ghc' package itself a boot library for
the purposes of this flag
Additionally, the allow-newer block in cabal.project-reinstall
was removed. This block was probably added because when the
libraries/Cabal submodule is too new relative to the cabal-install
executable, solving the setup-depends for any package with a custom
setup requires building an old Cabal (from Hackage) against the
in-tree version of base, and this can fail un-necessarily due to
tight version bounds on base. However, the blind allow-newer can
also cause the solver to go berserk and choose a stupid build plan
that has no business succeeding, and the failures when this happens
are dreadfully confusing. (See #23281 and #24363.)
Why does setup-depends solving insist on an old version of Cabal? See:
https://github.com/haskell/cabal/blob/0a0b33983b0f022b9697f7df3a69358ee9061a89/cabal-install/src/Distribution/Client/ProjectPlanning.hs#L1393-L1410
The right solution here is probably to use the in-tree cabal-install
from libraries/Cabal/cabal-install with the build-cabal target rather
than whatever the environment happens to provide. But this is left
for future work.

ci: Add support for ONLY_JOBS variable to trigger any validation pipeline
By setting the ONLY_JOBS variable to the name of the job (or multiple
jobs), the resulting
pipeline will include a validation job for that pipeline.
For example - if you set ONLY_JOBS="x86_64-linux-ubuntu22_04-validate"
then a ubuntu22_04 job will be included in the validation pipeline. This
is useful for testing specific jobs.

wasm: bump dyld v8 heap size limit
This patch adds `--max-old-space-size=8192` to wasm dyld shebang
arguments to bump V8 heap size limit. The default limit
(`heap_size_limit` returned by `v8.getHeapStatistics()`) is
dynamically determined and a bit too low under certain workloads, and
V8 would waste too much CPU time to garbage collect old generation
heap more aggressively. Bumping the limit to 8G doesn't imply dyld
would really take that much memory at run-time, but it lessens V8 heap
stress significantly.

Move defaulting code into a new module
GHC.Tc.Solver had reached 4,000 lines -- although quite a lot of them
are comments.
This MR
* Adds the new module GHC.Tc.Solver.Default, which has all the
complex, but well modularised, defaulting code
* Moves a bit of code from GHC.Tc.Solver into the existing
GHC.Tc.Solver.Solve. Notably solveWanteds and simplifyWantedsTcM,
which are called from GHC.Tc.Solver.Default
It's a pure refactor. No code changes.

hadrian: fix bindist executable wrapper logic for cross targets
This commit fixes an oversight of hadrian wrapper generation logic:
when doing cross compilation, `wrapper` is called on executable names
with cross prefix, therefore we must use `isSuffixOf` when matching to
take the cross prefix into account. Also add missing cross prefix to
ghci wrapper content and fix hsc2hs wrapper logic.

mkTick: Push ticks through unsafeCoerce#.
unsafeCoerce# doesn't exist at runtime so we should treat it like a Cast
for the purpose of mkTick.
This means if we have `{-# SCC foo #-} (unsafeCoerce# trivial_expr))` we
now push the scope part of the cost centre up to `trivial_expr` at which
point we can discard it completely if the expression is trivial enough.
This fixes #25212.

determinism: Interface re-export list det
In 'DocStructureItem' we want to make sure the 'Avails' are sorted, for
interface file determinism. This commit introduces 'DetOrdAvails', a
newtype that should only be constructed by sorting Avails with
'sortAvails' unless the avails are known to be deterministically
ordered. This newtype is used by 'DocStructureItem' where 'Avails' was
previously used to ensure the list of avails is deterministically sorted
by construction.
Note: Even though we order the constructors and avails in the interface
file, the order of constructors in the haddock output is still
determined from the order of declaration in the source. This was also
true before, when the list of constructors in the interface file <docs>
section was non-deterministic. Some haddock tests such as
"ConstructorArgs" observe this (check the order of constructors in
out/ConstructorArgs.html vs src/ConstructorArgs.hs vs its interface file)
The updated tests are caused by haddock corners where the order in the
source is not preserved (and was non-deterministic before this PR):
* Module header in the latex backend
* Re-export of pattern synonyms associated to a datatype (#25342)
Fixes #25304

Make DataCon workers strict in strict fields (#20749)
This patch tweaks `exprIsConApp_maybe`, `exprIsHNF` and friends, and Demand
Analysis so that they exploit and maintain strictness of DataCon workers. See
`Note [Strict fields in Core]` for details.
Very little needed to change, and it puts field seq insertion done by Tag
Inference into a new perspective: That of *implementing* strict field semantics.
Before Tag Inference, DataCon workers are strict. Afterwards they are
effectively lazy and field seqs happen around use sites. History has shown
that there is no other way to guarantee taggedness and thus the STG Strict Field
Invariant.
Knock-on changes:
* I reworked the whole narrative around "Tag inference".
It's now called "EPT enforcement" and I recycyled the different overview
Notes into `Note [EPT enforcement]`.
* `exprIsHNF` previously used `exprOkForSpeculation` on unlifted arguments
instead of recursing into `exprIsHNF`. That regressed the termination
analysis in CPR analysis (which simply calls out to `exprIsHNF`), so I made
it call `exprOkForSpeculation`, too.
* There's a small regression in Demand Analysis, visible in the changed test
output of T16859: Previously, a field seq on a variable would give that
variable a "used exactly once" demand, now it's "used at least once",
because `dmdTransformDataConSig` accounts for future uses of the field
that actually all go through the case binder (and hence won't re-enter the
potential thunk). The difference should hardly be observable.
* The Simplifier's fast path for data constructors only applies to lazy
data constructors now. I observed regressions involving Data.Binary.Put's
`Pair` data type.
* Unfortunately, T21392 does no longer reproduce after this patch, so I marked
it as "not broken" in order to track whether we regress again in the future.
Fixes #20749, the satisfying conclusion of an annoying saga (cf. the ideas
in #21497 and #22475).

I looked at T17516. It seems we do a few more simplifier iterations and end up
with a larger program. It seems that some things inline more, while other things
inline less. I don't see low-hanging fruit.
I also looked at MultiLayerModulesTH_OneShot. It appears we generate a strange
join point in the `getUnique` method of `Uniquable GHC.Unit.Types.Module` that
should better call-site inline, but does not. Perhaps with !11492.
NoFib does not seem affected much either:

I had a look at last-piece. Nothing changes in stg-final, but there is a bit
of ... movement around Data.Map.insert's use of GHC.Exts.lazy that is gone in
stg-final.

Some renaming
This is a pure refactor, tidying up some inconsistent naming:
isEqPred --> isEqClassPred
isEqPrimPred --> isEqPred
isReprEqPrimPred --> isReprEqPred
mkPrimEqPred --> mkNomEqPred
mkReprPrimEqPred --> mkReprEqPred
mkPrimEqPredRold --> mkEqPredRole
Plus I moved mkNomEqPred, mkReprEqPred, mkEqPredRolek
from GHC.Core.Coercion to GHC.Core.Predicate
where they belong. That means that Coercion imports Predicate
rather than vice versa -- better.

Fix optimisation of InstCo
It turned out (#25387) that the fix to #15725 was not quite right:
commit 48efbc04bd45d806c52376641e1a7ed7278d1ec7
Date: Mon Oct 15 10:25:02 2018 +0200
Fix #15725 with an extra Sym
Optimising InstCo is quite subtle, and the invariants surrounding
the LiftingContext in the coercion optimiser were not stated explicitly.
This patch refactors the InstCo optimisation, and documents these
invariants. See
* Note [Optimising InstCo]
* Note [The LiftingContext in optCoercion]
I also did some refactoring of course:
* Instead of a Bool swap-flag, I am not using GHC.Types.Basic.SwapFlag
* I added some invariant-checking the coercion-construction functions
in GHC.Core.Coercion.Opt. (Sadly these invariants don't hold during
typechecking, becuase the types are un-zonked, so I can't put these
checks in GHC.Core.Coercion.)

Add a missing tidy in UnivCo
We were failing to tidy the argument coercions of a UnivCo, which
led directly to #25391.
The fix is, happily, trivial.
I don't have a small repro case (it came up when building horde-ad,
which uses typechecker plugins). It should be possible to make a
repro case, by using a plugin (which builds a UnivCo) but I decided
it was not worth the bother. The bug is egregious and easily fixed.

This patch fixes foreign stub handling logic in `hscParsedDecls`.
Previously foreign stubs were simply ignored here, so any feature that

reuses `generateByteCode` logic and eliminates a large chunk of

Assert that ctEvCoercion is called on an equality
Calling 'ctEvCoercion' on non-equality constraints is always incorrect.
We add an assertion to this function to detect such cases; for example
a type-checking plugin might erroneously do this.

Remove unused USE_REPORT_PRELUDE code paths from the tree
This patch removes unused `USE_REPORT_PRELUDE` code paths from the
tree. They have been present since the first git revision
4fb94ae5e5d632748fa2e6c35e259eccc5a1a3f4, and might have been useful
for debugging purposes many years ago, but these code paths are never
actually built. Removing these ease maintenance of relevant modules in
the future, and also allows us to get rid of `CPP` extension in those
modules as a nice byproduct.

Make ApplicativeDo work with HsExpansions
testcase added: T24406
Issues Fixed: #24406, #16135
Code Changes:
- Remove `XStmtLR GhcTc` as `XStmtLR GhcRn` is now compiled to `HsExpr GhcTc`
- The expanded statements are guided by `GHC.Hs.Expr.TcFunInfo` which is used to decide
if the `XExpr GhcRn` is to be typechecked using `tcApp` or `tcExpr`
Note [Expanding HsDo with XXExprGhcRn] explains the change in more detail
