The `hadrian/doc/windows.md` file has falled out of date. In particular
it still points to the old GitHub repository, and uses incorrect path
to GHC. This patch fixes it.

-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

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

Otherwise the testsuite driver crashes when run multiple times with CLEANUP=NO

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.

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

Since the `$(docdir)` can be picked independently from the `$(libdir)`,
we need to make sure that that the `haddock-html` and `haddock-interface`
fields in the package DB (which is in the `$(libdir)`) get updated to
point to the appropriate places in the `$(docdir)`.
NB: in the make system, `ghc-cabal` would cover this sort of thing by
re-running `configure` on installation, but here we get away with a
couple lines of `sed` and a call to `ghc-pkg recache`.
Fixes #16202.

In Alp's refactoring of `getProgramContexts` he removed a call to
`getProgramContext` which was where the logic for this used to be
implemented.

The "worker" for a newtype is actually a function
with a small (compulsory) unfolding, namely a cast.
But the construction of this function was plain wrong
for newtype /instances/; it cast the arguemnt to the
family type rather than the representation type.
This never actually bit us because, in the case of a
family instance, we immediately cast the result to
the family type. So we get
\x. (x |> co1) |> co2
where the compositio of co1 and co2 is ill-kinded.
However the optimiser (even the simple optimiser)
just collapsed those casts, ignoring the mis-match
in the middle, so we never saw the problem.
Trac #16191 is indeed a dup of #16141; but the resaon
these tickets produce Lint errors is not the unnecessary
forcing; it's because of the ill-typed casts.
This patch fixes the ill-typed casts, properly. I can't
see a way to trigger an actual failure prior to this
patch, but it's still wrong wrong wrong to have ill-typed
casts, so better to get rid of them.

GHC has code to handle unsuffixed .so files that are linker scripts
pointing to the real shared library. The detection is done by parsing
the result of `dlerror()` after calling `dlopen()` and looking for
certain error strings. On musl libc, the error message is "Exec format
error", which happens to be `strerror(ENOEXEC)`:
```
$ cat tmp.c
#include <dlfcn.h>
#include <stdio.h>
int main(void) {
dlopen("libz.so", RTLD_NOW | RTLD_GLOBAL);
puts(dlerror());
return 0;
}
$ gcc -o tmp tmp.c
$ ./tmp
Error loading shared library libz.so: Exec format error
$
```
This change fixes the workaround to also work on musl libc.

It is correct to be `GhcTc` as the data type is for expressions which are inside splices
so they can be delayed until desugaring.

Summary:
When DeriveAnyClass and GeneralizedNewtypeDeriving are both enabled,
GHC prints out a warning that specifies the strategy it used to
derive a class. This patch updates the warning to mention that users
may pick a particular strategy by using DerivingStrategies.
