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.

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.

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  outdated - list all outdated diagnostic codes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: 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"

Fix several mistakes around free variables in iface breakpoints

Fixes #23612 , #23607, #23998 and #23666.

MR: !11026

The fingerprinting logic in `Iface.Recomp` failed lookups when processing decls containing breakpoints for two reasons:

* IfaceBreakpoint created binders for free variables instead of expressions

* When collecting free names for the dependency analysis for fingerprinting, breakpoint FVs were skipped

Refactor to combine HsLam and HsLamCase

This MR is pure refactoring (#23916):
* Combine `HsLam` and `HsLamCase`
* Combine `HsCmdLam` and `HsCmdLamCase`

This just arranges to treat uniformly
   \x -> e
   \case pi -> ei
   \cases pis -> ie

In the exising code base the first is treated differently
to the latter two.

No change in behaviour.

More specifics:

* Combine `HsLam` and `HsLamCase` (constructors of `Language.Haskell.Syntax.Expr.HsExpr`) into one data construtor covering
  * Lambda
  * `\case`
  * `\cases`

* The new `HsLam` has an argument of type `HsLamVariant` to distinguish the three cases.

* Similarly, combine `HsCmdLam` and `HsCmdLamCase` (constructors of `Language.Haskell.Syntax.Expr.HsCmd` ) into one.

* Similarly, combine `mkHsLamPV` and `mkHsLamCasePV` (methods of class `DisambECP`) into one. (Thank you Alan Zimmerman.)

* Similarly, combine `LambdaExpr` and `LamCaseAlt` (constructors of `Language.Haskell.Syntax.Expr.HsMatchContext`) into one: `LamAlt` with a `HsLamVariant` argument.

* Similarly, combine `KappaExpr` and `ArrowLamCaseAlt` (constructors of `Language.Haskell.Syntax.Expr.HsArrowMatchContext`) into one: `ArrowLamAlt` with a `HsLamVariant` argument.

* Similarly, combine `PsErrLambdaInPat` and `PsErrLambdaCaseInPat` (constructors of `GHC.Parser.Errors.Ppr.PsError`) into one.

* In the same `PsError` data type, combine `PsErrLambdaCmdInFunAppCmd` and `PsErrLambdaCaseCmdInFunAppCmd` into one.

* In the same `PsError` data tpye, combine `PsErrLambdaInFunAppExpr` and `PsErrLambdaCaseInFunAppExpr` into one.

p* Smilarly combine `ExpectedFunTyLam` and `ExpectedFunTyLamCase` (constructors of `GHC.Tc.Types.Origin.ExpectedFunTyOrigin`) into one.

Phew!

EPA: Replace Monoid with NoAnn

We currently use the Monoid class as a constraint on Exact Print
Annotation functions, so we can use mempty. But this leads to
requiring Semigroup instances too, which do not always make sense.

Instead, introduce a class NoAnn, with a function noAnn analogous to
mempty.

configure: Fix #21712 again

This is a bit of a shot in the dark to fix #24033, which appears to be
another instance of #21712. For some reason the ld-override logic
*still* appears to be active on Darwin targets (or at least one).
Consequently, on misconfigured systems we may choose a non-`ld64`
linker.

It's a bit unclear exactly what happened in #24033 but ultimately the
check added for #21712 was not quite right, checking for the
`ghc_host_os` (the value of which depends upon the bootstrap compiler)
instead of the target platform. Fix this.

Fixes #24033.

Revert "Pass preprocessor options to C compiler when building foreign C files (#16737)"

This reverts commit 1c18d3b41f897f34a93669edaebe6069f319f9e2.

`-optP` should pass options to the preprocessor, that might be a very
different program to the C compiler, so passing the options to the C
compiler is likely to result in `-optP` being useless.

Ensure unconstrained instance dictionaries get IPE info

In the `StgRhsCon` case of `GHC.Stg.Debug.collectStgRhs`, we were not coming up
with an initial source span based on the span of the binder, which was causing
instance dictionaries without dynamic superclass constraints to not have source
locations in their IPE info. Now they do.

Resolves #24005
