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Remove outdated CPP in compiler/* and template-haskell/*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

If we have multiple defaulting plugins, then we should zonk in between them

after any defaulting has taken place, to avoid a defaulting plugin seeing
a metavariable that has already been filled.

Fixes #23821.
