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

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).

Implement MultilineStrings (#24390)
This commit adds support for multiline strings, proposed at
https://github.com/ghc-proposals/ghc-proposals/pull/569.
Multiline strings can now be written as:
myString =
"""
this is a
multiline string
"""
The multiline string will have leading indentation stripped away.
Full details of this post-processing may be found at the new
GHC.Parser.String module.
In order to cleanly implement this and maximize reusability, I
broke out the lexing logic for strings out of Lexer.x into a
new GHC.Parser.String module, which lexes strings with any
provided "get next character" function. This also gave us the
opportunity to clean up this logic, and even optimize it a bit.
With this change, parsing string literals now takes 25% less
time and 25% less space.

hi: Deterministic ImportedMods in Usages
The `mi_usages` field of the interface files must use a deterministic
list of `Usage`s to guarantee a deterministic interface. However, this
list was, in its origins, constructed from a `ModuleEnv` which uses a
non-deterministic ordering that was leaking into the interface.
Specifically, ImportedMods = ModuleEnv ... would get converted to a list and
then passed to `mkUsageInfo` to construct the Usages.
The solution is simple. Back `ImportedMods` with a deterministic map.
`Map Module ...` is enough, since the Ord instance for `Module` already
uses a stable, deterministic, comparison.
Fixes #25131

testsuite: extend size performance tests with gzip (fixes #25046)
The main purpose is to create tests for minimal app (hello world and its variations, i.e. unicode used) distribution size metric.
Many platforms support distribution in compressed form via gzip. It would be nice to collect information on how much size is taken by the executional bundle for each platform at minimal edge case.
2 groups of tests are added:
1. We extend javascript backend size tests with gzip-enabled versions for all cases where an optimizing compiler is used (for now it is google closure compiler).
2. We add trivial hello world tests with gzip-enabled versions for all other platforms at CI pipeline where no external optimizing compiler is used.

Cmm: don't perform unsound optimizations on 32-bit compiler hosts
- beef61351b240967b49169d27a9a19565cf3c4af enabled the use of
MO_Add/MO_Sub for 64-bit operations in the C and LLVM backends
- 6755d833af8c21bbad6585144b10e20ac4a0a1ab did the same for the x86 NCG
backend
However we store some literal values as `Int` in the compiler. As a
result, some Cmm optimizations transformed target 64-bit literals into
compiler `Int`. If the compiler is 32-bit, this leads to computing with
wrong literals (see #24893 and #24700).
This patch disables these Cmm optimizations for 32-bit compilers. This
is unsatisfying (optimizations shouldn't be compiler-word-size
dependent) but it fixes the bug and it makes the patch easy to backport.
A proper fix would be much more invasive but it shall be implemented in
the future.

RTS: remove hack to force old cabal to build a library with only JS sources
Need to extend JSC externs with Emscripten RTS definitions to avoid
JSC_UNDEFINED_VARIABLE errors when linking without the emcc rts.
Fix #25138
Some recompilation avoidance tests now fail. This is tracked with the
other instances of this failure in #23013. My hunch is that they were
working by chance when we used the emcc linker.
