Bignum: implement integerPowMod (#18427)
Incidentally fix powModInteger which was crashing in integer-gmp for
negative exponents when the modular multiplicative inverse for the base
didn't exist. Now we compute it explicitly with integerRecipMod so that
every backend returns the same result without crashing.

Workaround for #18623: GHC crashes bc. under rlimit for vmem it will reserve
_all_ of it, leaving nothing for, e.g., thread stacks.
Fix will only allocate 2/3rds and check whether remainder is at least large
enough for minimum amount of thread stacks.

Preserve as-parsed arrow type for HsUnrestrictedArrow
When linear types are disabled, HsUnrestrictedArrow is treated as
HslinearArrow.
Move this adjustment into the type checking phase, so that the parsed
source accurately represents the source as parsed.
Closes #18791

ApiAnnotations : preserve parens in GADTs
A cleanup in 7f418acf61e accidentally discarded some parens in
ConDeclGADT.
Make sure these stay in the AST in a usable format.
Also ensure the AnnLolly does not get lost in a GADT.

Bignum: match on small Integer/Natural
Previously we only matched on *variables* whose unfoldings were a ConApp
of the form `IS lit#` or `NS lit##`. But we forgot to match on the
ConApp directly... As a consequence, constant folding only worked after
the FloatOut pass which creates bindings for most sub-expressions. With
this patch, matching on bignums works even with -O0 (see bignumMatch
test).

[macOS] improved runpath handling
In b592bd98ff25730bbe3c13d6f62a427df8c78e28 we started using
-dead_strip_dylib on macOS when lining dynamic libraries and binaries.
The underlying reason being the Load Command Size Limit in macOS
Sierra (10.14) and later.
GHC will produce @rpath/libHS... dependency entries together with a
corresponding RPATH entry pointing to the location of the libHS...
library. Thus for every library we produce two Load Commands. One to
specify the dependent library, and one with the path where to find it.
This makes relocating libraries and binaries easier, as we just need to
update the RPATH entry with the install_name_tool. The dynamic linker
will then subsitute each @rpath with the RPATH entries it finds in the
libraries load commands or the environement, when looking up @rpath
relative libraries.
-dead_strip_dylibs intructs the linker to drop unused libraries. This in
turn help us reduce the number of referenced libraries, and subsequently
the size of the load commands. This however does not remove the RPATH
entries. Subsequently we can end up (in extreme cases) with only a
single @rpath/libHS... entry, but 100s or more RPATH entries in the Load
Commands.
This patch rectifies this (slighly unorthodox) by passing *no* -rpath
arguments to the linker at link time, but -headerpad 8000. The
headerpad argument is in hexadecimal and the maxium 32k of the load
command size. This tells the linker to pad the load command section
enough for us to inject the RPATHs later. We then proceed to link the
library or binary with -dead_strip_dylibs, and *after* the linking
inspect the library to find the left over (non-dead-stripped)
dependencies (using otool). We find the corresponding RPATHs for each
@rpath relative dependency, and inject them into the library or binary
using the install_name_tool. Thus achieving a deadstripped dylib (and
rpaths) build product.
We can not do this in GHC, without starting to reimplement a dynamic
linker as we do not know which symbols and subsequently libraries are
necessary.
