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.

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.

locations in their IPE info. Now they do.

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.

When the offset doesn't fit into the immediate we now just reuse the
general getRegister' code path which is well optimized to compute the
offset into a register instead of a special case for CmmRegOff.
This means we generate a lot less code under certain conditions which is
why performance metrics for these improve.

These are for heap allocation, a strictly RTS concern.
All of this should boil down to `AC_DEFINE` not `AC_SUBST`, so it
belongs in the RTS configure and should be safe to move without
modification.
The RTS configure one has a new
```
AC_CHECK_SIZEOF([void *])
```
that the top-level configure version didn't have, so that
`ac_cv_sizeof_void_p` is defined. Once more code is moved over in latter
commits, that can go away.

It does however add "xr" indiscriminatly to .text sections
even if splitSections is disabled. This leads to the assembler saying:

- A step towards killing `tcSyntaxOp`
- Fixes #18324 #20020 #23147 #22788 #15598 #22086 #21206
- Note [Expanding HsDo with HsExpansion] in `GHC.Tc.Gen.Do` explains change in detail
- Note Note [Doing HsExpansion in the Renamer vs Typechecker] in `GHC.Rename.Expr` expains the rational of doing expansions in type checker as opposed to in the renamer
- New datatypes to make this expansion work:
`GHC.Hs.Expr.XXExprGhcRn`: It contains
1. Expansion bits for Expressions, Statements and Patterns in (`ExpandedThingRn`)
2. `PopErrCtxt` a special GhcRn Phase only artifcat to pop the previous error message in the error context stack
- `GHC.Basic.Origin` now tracks the reason for expansion in case of Generated
This is useful for type checking cf. `GHC.Tc.Gen.Expr.tcExpr` case for `HsLam`
- Ensures warnings such as
1. Pattern mach checks
2. Failable patterns
3. non-() return in body statements are preserved
- Expansions inside Template haskell also work without issues.
- Testcases:
* T18324 T20020 T23147 T22788 T15598 T22086
* T23147b (error message check),
* DoubleMatch (match inside a match for pmc check)
* pattern-fails (check pattern match with non-refutable pattern, eg. newtype)
* Simple-rec (rec statements inside do statment)
* T22788 (code snippet from #22788)
* DoExpanion1 (Error messages for body statments)
* DoExpansion2 (Error messages for bind statements)
* DoExpansion3 (Error messages for let statements)
