Deriving-via one-shot strict state Monad instances
A small refactor to use deriving via GHC.Utils.Monad.State.Strict
Monad instances for state Monads with unboxed/strict results which all
re-implemented the one-shot trick in the instance and used unboxed
tuples:
* CmmOptM in GHC.Cmm.GenericOpt
* RegM in GHC.CmmToAsm.Reg.Linear.State
* UniqSM in GHC.Types.Unique.Supply

Only lookup ghcversion.h file in the RTS include-dirs by default.
The code was introduced in 3549c952b535803270872adaf87262f2df0295a4.
It used `getPackageIncludePath` which name doesn't convey that it looks
into all include paths of the preload units too. So this behavior is
probably unintentional and it should be ok to change it.
Fix #25106

driver: Fix -Wmissing-home-modules when multiple units have the same module name
It was assumed that module names were unique but that isn't true with
multiple units.
The fix is quite simple, maintain a set of `(ModuleName, UnitId)` and
query that to see whether the module has been specified.
Fixes #25122

PMC: suggest in-scope COMPLETE sets when possible
This commit modifies GHC.HsToCore.Pmc.Solver.generateInhabitingPatterns
to prioritise reporting COMPLETE sets in which all of the ConLikes
are in scope. This avoids suggesting out of scope constructors
when displaying an incomplete pattern match warning, e.g. in
baz :: Ordering -> Int
baz = \case
EQ -> 5
we prefer:
Patterns of type 'Ordering' not matched:
LT
GT
over:
Patterns of type 'Ordering' not matched:
OutOfScope
Fixes #25115

Print exception metadata in default handler
CLC proposals 231 and 261:
- Add exception type metadata to SomeException's displayException.
- Add "Exception" header to default exception handler.

Type syntax in expressions (#24159, #24572, #24226)
This patch extends the grammar of expressions with syntax that is
typically found only in types:
* function types (a -> b), (a ->. b), (a %m -> b)
* constrained types (ctx => t)
* forall-quantification (forall tvs. t)
The new forms are guarded behind the RequiredTypeArguments extension,
as specified in GHC Proposal #281. Examples:
{-# LANGUAGE RequiredTypeArguments #-}
e1 = f (Int -> String) -- function type
e2 = f (Int %1 -> String) -- linear function type
e3 = f (forall a. Bounded a => a) -- forall type, constraint
The GHC AST and the TH AST have been extended as follows:
syntax | HsExpr | TH.Exp
---------------+----------+--------------
a -> b | HsFunArr | ConE (->)
a %m -> b | HsFunArr | ConE FUN
ctx => t | HsQual | ConstrainedE
forall a. t | HsForAll | ForallE
forall a -> t | HsForAll | ForallVisE
Additionally, a new warning flag -Wview-pattern-signatures has been
introduced to aid with migration to the new precedence of (e -> p :: t).
