llvmGen: Introduce infrastructure for module flag metadata

llvmGen: Don't pass stack alignment via command line
As of https://reviews.llvm.org/D103048 LLVM no longer supports the
`-stack-alignment=...` flag. Instead this information is passed via a
module flag metadata node.
This requires dropping support for LLVM 11 and 12.
Fixes #23870

EPA: Keep track of "in" token for WarningTxt category
A warning can now be written with a category, e.g.
{-# WARNInG in "x-c" e "d" #-}
Keep track of the location of the 'in' keyword and string, as well as
the original SourceText of the label, in case it uses character escapes.

CorePrep: Eliminate EmptyCase and unsafeEqualityProof in CoreToStg instead
We eliminate EmptyCase by way of `coreToStg (Case e _ _ []) = coreToStg e` now.
The main reason is that it plays far better in conjunction with eta expansion
(as we aim to do for arguments in CorePrep, #23083), because we can discard
any arguments, `(case e of {}) eta == case e of {}`, whereas in `(e |> co) eta`
it's impossible to discard the argument.

Remove ScopedTypeVariables => TypeAbstractions
This commit implements [amendment 604](https://github.com/ghc-proposals/ghc-proposals/pull/604/)
to [GHC proposal 448](https://github.com/ghc-proposals/ghc-proposals/pull/448)
by removing the implication of language extensions
ScopedTypeVariables => TypeAbstractions
To limit breakage, we now allow type arguments in constructor patterns
when both ScopedTypeVariables and TypeApplications are enabled, but
we emit a warning notifying the user that this is deprecated behaviour
that will go away starting in GHC 9.12.
Fixes #23776

Make some evidence uses reachable by toHie
Resolves #23540, #23120
This adds spans to certain expressions in the typechecker and renamer,
and lets 'toHie' make use of those spans. Therefore the relevant
evidence uses for the following syntax will now show up under the
expected nodes in 'HieAst's:
- Overloaded literals ('IsString', 'Num', 'Fractional')
- Natural patterns and N+k patterns ('Eq', 'Ord', and instances from the
overloaded literals being matched on)
- Arithmetic sequences ('Enum')
- Monadic bind statements ('Monad')
- Monadic body statements ('Monad', 'Alternative')
- ApplicativeDo ('Applicative', 'Functor')
- Overloaded lists ('IsList')
Also see Note [Source locations for implicit function calls]
In the process of handling overloaded lists I added an extra 'SrcSpan'
field to 'VAExpansion' - this allows us to more accurately reconstruct
the locations from the renamer in 'rebuildHsApps'. This also happens to
fix #23120.
See the additions to Note [Looking through HsExpanded]

Export setInertSet from GHC.Tc.Solver.Monad
We used to export getTcSInerts and setTcSInerts from GHC.Tc.Solver.Monad.
These got renamed to getInertSet/setInertSet in e1590ddc. That commit also removed
the export of setInertSet, but that function is useful for the GHC API.

Don't bundle children for non-parent Avails
We used to bundle all children of the parent Avail with things that
aren't the parent, e.g. with
class C a where
type T a
meth :: ..
we would bundle the whole Avail (C, T, meth) with all of C, T and meth,
instead of only with C.
Avoiding this fixes #23570

Metric Decrease:

Metric Increase:
T13386
T8095
T8095 ghc/alloc decreased on x86_64, but increased on aarch64.
T13386 ghc/alloc decreased on x86_64-windows, but increased on other platforms.
Neither has anything to do with `foldl'`, so I conclude that both are flaky.

Fix wrong role in mkSelCo_maybe
In the Lint failure in #23938, we start with a coercion Refl :: T a ~R T a,
and call mkSelCo (SelTyCon 1 nominal) Refl.
The function incorrectly returned Refl :: a ~R a. The returned role
should be nominal, according to the SelCo rule:
co : (T s1..sn) ~r0 (T t1..tn)
r = tyConRole tc r0 i
----------------------------------
SelCo (SelTyCon i r) : si ~r ti
In this test case, r is nominal while r0 is representational.

Add warning for badly staged types.
Resolves #23829.
The stage violation results in out-of-bound names in splices.
Technically this is an error, but someone might rely on this!?
Internal changes:
- we now track stages for TyVars.
- thLevel (RunSplice _) = 0, instead of panic, as reifyInstances does
in fact rename its argument type, and it can contain variables.

rts/RtsSymbols: Add AArch64 outline atomic operations
Fixes #22012 by adding the symbols described in
https://github.com/llvm/llvm-project/blob/main/llvm/docs/Atomics.rst#libcalls-atomic.
Ultimately this would be better addressed by #22011, but this is a first
step in the right direction and fixes the immediate symptom.
Note that we dropped the `__arch64_cas16` operations as these provided
by all platforms's compilers. Also, we don't link directly against the
libgcc/compiler-rt definitions but rather provide our own wrappers to
work around broken toolchains (e.g. https://bugs.gentoo.org/868018).

nonmoving: introduce a family of dense allocators
Supplement the existing power 2 sized nonmoving allocators with a family
of dense allocators up to a configurable threshold.
This should reduce waste from rounding up block sizes while keeping the
amount of allocator sizes manageable.
This patch:
- Adds a new configuration option `--nonmoving-dense-allocator-count`
to control the amount of these new dense allocators.
- Adds some constants to `NonmovingAllocator` in order to keep
marking fast with the new allocators.

Use correct FunTyFlag in adjustJoinPointType
As the Lint error in #23952 showed, the function adjustJoinPointType
was failing to adjust the FunTyFlag when adjusting the type.
I don't think this caused the seg-fault reported in the ticket,
but it is definitely. This patch fixes it.
It is tricky to come up a small test case; Krzysztof came up with
this one, but it only triggers a failure in GHC 9.6.

base: Advertise linear time of readFloat
As noted in #23538, `readFloat` has runtime that scales nonlinearly in
the size of its input. Consequently, its use on untrusted input can
be exploited as a denial-of-service vector. Point this out and suggest
use of `read` instead.
See #23538.

Adjust reporting of unused tyvars in data FamInsts
This commit adjusts the validity checking of data family
instances to improve the reporting of unused type variables.
See Note [Out of scope tvs in data family instances] in GHC.Tc.Validity.
The problem was that, in a situation such as
data family D :: Type
data instance forall (d :: Type). D = MkD
the RHS passed to 'checkFamPatBinders' would be the TyCon app
R:D d
which mentions the type variable 'd' quantified in the user-written
forall. Thus, when computing the set of unused type variables in
the RHS of the data family instance, we would find that 'd' is used,
and report a strange error message that would say that 'd' is not
bound on the LHS.
To fix this, we special-case the data-family instance case,
manually extracting all the type variables that appear in the
arguments of all the data constructores of the data family instance.
Fixes #23778

Unused tyvars in FamInst: only report user tyvars
This commit changes how we perform some validity checking for
coercion axioms to mirror how we handle default declarations for
associated type families. This allows us to keep track of whether
type variables in type and data family instances were user-written
or not, in order to only report the user-written ones in
"unused type variable" error messages.
Consider for example:
{-# LANGUAGE PolyKinds #-}
type family F
type instance forall a. F = ()
In this case, we get two quantified type variables,
(k :: Type) and (a :: k); the second being user-written, but the first
is introduced by the typechecker. We should only report 'a' as being
unused, as the user has no idea what 'k' is.
Fixes #23734

hadrian: Make it easier to debug Cabal configure
Right now, output is squashed. This make per-package configure scripts
extremely hard to maintain, because we get vague "library is missing"
errors when the actually probably is usually completely unrelated except
for also involving the C/C++ toolchain.
(I can always pass `-VVV` to Hadrian locally, but these errors are
subtle and I often cannot reproduce them locally!)
`--disable-option-checking` was added back in
75c6e0684dda585c37b4ac254cd7a13537a59a91 but seems to be a bit overkill;
if other flags are passed that are not recognized behind the two from
Cabal mentioned in the former comment, we *do* want to know about it.

Add same LD hack to ghc-toolchain
In the ./configure script, if you pass the `LD` variable then this has
the effect of stopping use searching for a linker and hence passing
`-fuse-ld=...`.
We want to emulate this logic in ghc-toolchain, if a use explicilty
specifies `LD` variable then don't add `-fuse-ld=..` with the goal of
making ./configure and ghc-toolchain agree on which flags to use when
using the C compiler as a linker.
This is quite unsavoury as we don't bake the choice of LD into the
configuration anywhere but what's important for now is making
ghc-toolchain and ./configure agree as much as possible.
See #23857 for more discussion

Check for --target linker flag separately to C compiler
There are situations where the C compiler doesn't accept `--target` but

In particular with old gcc toolchains, the C compiler doesn't support
--target but when used as a linker it does.

hadrian: Don't pass LDFLAGS as a --configure-arg to cabal configure
We don't have anything sensible to set LDFLAGS to because the "linker"
flags we have are actually flags we pass to the C compiler when it's
used as a linker.
Likewise stop passing -gcc-options which mixed together linker flags and
non-linker flags. There's no guarantee the C compiler will accept both
of these in each mode.
