Trac #16183 was caused by TH conversion (in `Convert`) not properly
inserting parentheses around occurrences of explicit signatures where
appropriate, such as in applications, function types, and type family
equations. Solution: use `parenthesizeHsType sigPrec` in these
places. While I was in town, I also updated `nlHsFunTy` to do the
same thing.

Should be no change in behavior, but this makes the control
flow a little more apparent.

Why is it so hard to delete a directory's contents without deleting the
directory itself in Windows? This will forever remain a mystery.

Add missing color mappings to regDotColor for amd64.
Also set fakeRegs to red instead of xmm regs.

Although we should use 'AC_ARG_ENABLE' for boolean flags, it also
means options get named '--enable-*', not '--with-*'. This should
unbreak the --with-intree-gmp option.

-ddump-json didn't work with --interactive as --interactive overwrote
the log_action in terms of defaultLogAction.

As pointed out in #16085, these ghci tests are fragile in the unregisterised
way.

For an API annotation to be useful, it must not occur before the span
it is enclosed in.

So, for check-api-annotation output, a line such as

((Test16212.hs:3:22-36,AnnOpenP), [Test16212.hs:3:21]),

should be flagged as an error, as the AnnOpenP location of 3:21
precedes its enclosing span of 3:22-26.

This patch does this.

Closes #16217

It imports System.Posix.IO.

Otherwise the testsuite driver crashes when run multiple times with CLEANUP=NO
on a test containing such extra_files.

Previously `thNameToGhcName` was calling `lookupOrigNameCache` directly, which
failed to handle the case that the name wasn't already in the name cache. This
happens, for instance, when the name was in scope in a plugin being used during
compilation but not in scope in the module being compiled. In this case we the
interface file containing the name won't be loaded and `lookupOrigNameCache`
fails. This was the cause of #16104.

The solution is simple: use the nicely packaged `lookupOrigIO` instead.

Previously testing code-generation for ISA extensions was nearly impossible
since we had no ability to determine whether the host supports the needed
extension. Here we fix this by introducing a simple /proc/cpuinfo-based
testsuite predicate. We really ought to

Apparently GitLab CI defaults to declaring all jobs of the previous
stage as dependencies of a job. This meant that we would end up
downloading all of our binary distributions during the `cleanup` stage,
eating up a truly remarkable amount of S3 tranfers.

See #16085.

It's pretty unlikely we will be going back to circleci at this point

Although the Haddock's for `shiftL` and `shiftR` do require the number
of bits to be non-negative, we should still check this before calling
out to primitives (which also have undefined behaviour for negative bit
shifts).

If a user _really_ wants to bypass checks that the number of bits is
sensible, they already have the aptly-named `unsafeShiftL`/`unsafeShiftR`
at their disposal.

See #16111.

Summary:
This adds top-level configure flags '--with-intree-gmp' and
'--with-framework-preferred', both of which are especially relevant
on MacOS.

Besides gaining two new flags, Hadrian also had to be taught what to
do with the 'framework' in .cabal files.

Test Plan:
./boot && ./configure --with-intree-gmp && ./hadrian/build.sh
./boot && ./configure --with-gmp-framework-preferred && ./hadrian/build.sh # on macos
