Move lib{numa,dw} defines to RTS configure

Clean up the m4 to handle the auto case always and be more consistent.
Also simplify the CPP --- we should always have both headers if we are
using libnuma.

"side effects" (AC_DEFINE, and AC_SUBST) are removed from the macros to
better separate searching from actions taken based on search results.
This might seem overkill now, but will make shuffling logic between
configure scripts easier later.

The macro comments are converted from `dnl` to `#` following the
recomendation in
https://www.gnu.org/software/autoconf/manual/autoconf-2.71/html_node/Macro-Definitions.html

Shuffle libzstd configuring between scripts

Like the prior commit for libdw and libnuma, `AC_DEFINE` to RTS
configure, `AC_SUBST` goes to the top-level configure script, and the
documentation of the m4 macro is improved.

Move `FP_ARM_OUTLINE_ATOMICS` to RTS configure

It is just `AC_DEFINE` it belongs there instead.

Move mmap in the runtime linker check to the RTS configure

`AC_DEFINE` should go there instead.

Refactor uses of `partitionEithers . map`

This patch changes occurences of the idiom
`partitionEithers (map f xs)` by the simpler form
`partitionWith f xs` where `partitionWith` is the utility function
defined in `GHC.Utils.Misc`.

Resolves: #23953

Refactor uses of `partitionEithers <$> mapM f xs`

This patch changes occurences of the idiom
`partitionEithers <$> mapM f xs` by the simpler form
`partitionWithM f xs` where `partitionWithM` is a utility function
newly added to `GHC.Utils.Misc`.

Mark `GHC.Utils.Misc.partitionWithM` as inlineable

This patch adds an `INLINEABLE` pragma for `partitionWithM` to ensure
that the right-hand side of the definition of this function remains
available for specialisation at call sites.

Refactor: introduce stgArgRep

The function 'stgArgType' returns the type in STG. But this violates
the abstraction: in STG we're supposed to operate on PrimReps.

This introduces
stgArgRep ty = typePrimRep (stgArgType ty)
stgArgRep1 ty = typePrimRep1 (stgArgType ty)
stgArgRep_maybe ty = typePrimRep_maybe (stgArgType ty)

stgArgType is still directly used for unboxed tuples (should be fixable), FFI
and in ticky.

Fix TH pretty-printer's parenthesization

Add a testcase for #17564

The code in the ticket relied on the behaviour of Derived constraints.
Derived constraints were removed in GHC 9.4 and now the code works
as expected.

lint-codes: add new modes of operation

This commit adds two new modes of operation to the lint-codes
utility:

  list - list all statically used diagnostic codes
  outdated - list all outdated diagnostic codes

The previous behaviour is now:

  test - test consistency and coverage of diagnostic codes

lint codes: avoid using git-grep

We manually traverse through the filesystem to find the diagnostic codes
embedded in .stdout and .stderr files, to avoid any issues with old
versions of grep.

Fixes #23843

lint-codes: add Hadrian targets

This commit adds new Hadrian targets:

  codes, codes:used - list all used diagnostic codes
  codes:outdated - list outdated diagnostic codes

This allows users to easily query GHC for used and outdated
diagnostic codes, e.g.

  hadrian/build -j --flavour=<..> codes

will list all used diagnostic codes in the command line by running
the lint-codes utility in the "list codes" mode of operation.

The diagnostic code consistency and coverage test is still run as usual,
through the testsuite:

  hadrian/build test --only="codes"

Fixes #18324 #23147 #20020
Expands do notation before typechecking using `HsExpansion`
- Adds testcases T18324, T18324b, DoubleMatch
Expands
- Do statements
- Monadic do statements
- monadic fix blocks
- make sure fail is used for pattern match failures in bind statments
- Makes sure unused binds generate warnings
- runs the pattern match check in generated lambda exprs to avoid getting suprious pattern match failures. c.f. pmcheck/should_compile/DoubleMatch.hs
- PopSrcSpan in HsExpr to pop error context
- Discards default monad fail alternatives that are spuriously generated
- Make sure we check for generated loc span for checking if the (>>) is user written or expanded for /do/ purposes

- Add PopSrcSpan (XXExprGhcRn) in appropriate places while expanding statements
- correct source spans displayed for warnDiscardedDoBindings
- use `mkExpandStmt` to store original stmts along with expanded expr for using the right context for error message printing
- improves error messages for applicative do
- remove special case from isMatchContextPmChecked (long distance info is now properly propogated)
- set correct src spans to statement expansions
- Match ctxt while type checking HsLam is different if the lambda match is due to an expression generated from a do block
- call tcExpr and not tcApp in PopSrcSpan so make sure impredicativity works fine
- look into XExprs in tcInferAppHead_maybe for infering the type to make T18324 typecheck and run

- make the ExpandedStmt generated expression location-less
- Introduce ExpansionStmt for proper `hsSplitApps`
- Introduce `VAExpansionStmt` that is just like `VAExpansion` but for statements
- Aligning expand stmt context pushing on error stack.
- Pop error context while checking do expansion generated GRHSs inside HsLam so that we do not print the previous statement error context
- makes template haskell happy
- some fix for let expansions
- refactor tcExpr into tcExpr and tcXExpr
- adding Note and references
- make monad fail errors normal again
