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.

Remove outdated CPP in compiler/* and template-haskell/*

The boot compiler was bumped to 9.4 in cebb5819b43.
There is no point supporting older GHC versions with CPP.

testsuite: Add regression test for #23864

commit 59202c800f2c97c16906120ab2561f6e1556e4af

    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

.stderr: ScopedTypeVariables =/> TypeAbstractions

This commit accepts testsuite changes for the changes in the previous
commit, which mean that TypeAbstractions is no longer implied by
ScopedTypeVariables.

Add test for #23540

`T23540.hs` makes use of `explainEv` from `HieQueries.hs`, so
`explainEv` has been moved to `TestUtils.hs`.

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]

Misc cleanup

- Builtin.PrimOps: ReturnsAlg was used only for unboxed tuples.
  Rename to ReturnsTuple.
- Builtin.Utils: use SDoc for a panic message.
  The comment about <<details unavailable>> was obsoleted by e8d356773b56.
- TagCheck: fix wrong logic. It was zipping a list 'args' with its
  version 'args_cmm' after filtering.
- Core.Type: remove an outdated 1999 comment about unlifted polymorphic types
- hadrian: remove leftover debugging print

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.

driver: Check transitive closure of haskell package dependencies when deciding whether to relink

We were previously just checking whether direct package dependencies had
been modified. This caused issues when compiling without optimisations
as we wouldn't relink the direct dependency if one of its dependenices
changed.

Fixes #23724
