Don't consider large byte arrays/compact regions pinned.

Workaround for #22255 which showed how treating large/compact regions
as pinned could cause segfaults.

hadrian bindist: Install manpages to share/man/man1/ghc.1

When the installation makefile was copied over the manpages were no
longer installed in the correct place. Now we install it into share/man/man1/ghc.1
as the make build system did.

Fixes #22371

rts: Drop paths from configure from cabal file

A long time ago we would rely on substitutions from the configure script
to inject paths of the include and library directories of libffi and
libdw. However, now these are instead handled inside Hadrian when
calling Cabal's `configure` (see the uses of `cabalExtraDirs` in
Hadrian's `Settings.Packages.packageArgs`).

While the occurrences in the cabal file were redundant, they did no
harm. However, since b5c714545abc5f75a1ffdcc39b4bfdc7cd5e64b4 they have
no longer been interpolated. @mpickering noticed the suspicious
uninterpolated occurrence of `@FFIIncludeDir@` in #22595,
prompting this commit to finally remove them.

JS: fix support for -outputdir (#22641)

The `-outputdir` option wasn't correctly handled with the JS backend
because the same code path was used to handle both objects produced by
the JS backend and foreign .js files. Now we clearly distinguish the
two in the pipeline, fixing the bug.

Refactor mkRuntimeError

This patch fixes #22634.  Because we don't have TYPE/CONSTRAINT
polymorphism, we need two error functions rather than one.

I took the opportunity to rname runtimeError to impossibleError,
to line up with mkImpossibleExpr, and avoid confusion with the
genuine runtime-error-constructing functions.

base: Fix event manager shutdown race on non-Linux platforms

During shutdown it's possible that we will attempt to use a closed fd
to wakeup another capability's event manager. On the Linux eventfd path
we were careful to handle this. However on the non-Linux path we failed
to do so. Fix this.

nonmoving: Eliminate race in bump_static_flag

To ensure that we don't race with a mutator entering a new CAF we take
the SM mutex before touching static_flag. The other option here would be
to instead modify newCAF to use a CAS but the present approach is a bit
safer.

nonmoving: Fix races in collector status tracking

Mark a number of accesses to do with tracking of the status of the
concurrent collection thread as atomic. No interesting races here,
merely necessary to satisfy TSAN.

nonmoving: Refactor update remembered set initialization

This avoids a lock inversion between the storage manager mutex and
the stable pointer table mutex by not dropping the SM_MUTEX in
nonmovingCollect. This requires quite a bit of rejiggering but it
does seem like a better strategy.

nonmoving: Make bitmap accesses atomic

This is a benign race on any sensible hard since these are byte
accesses. Nevertheless, atomic accesses are necessary to satisfy
TSAN.

nonmoving: Fix benign race in update remembered set check

Relaxed load is fine here since we will take the lock before looking at
the list.

nonmoving: Fix race in shortcutting

We must use an acquire load to read the info table pointer since if we
find an indirection we must be certain that we see the indirectee.

compiler: Ensure that GHC toolchain is first in search path

As noted in #22561, it is important that GHC's toolchain look
first for its own headers and libraries to ensure that the
system's are not found instead. If this happens things can
break in surprising ways (e.g. see #22561).

head.hackage: Use slow-validate bindist for linting jobs

This enables the SLOW_VALIDATE env var for the linting head.hackage
jobs, namely the jobs enabled manually, by the label or on the nightly
build now use the deb10-numa-slow-validate bindist which has assertions
enabled.

See #22623 for a ticket which was found by using this configuration
already!

The head.hackage jobs triggered by upstream CI are now thusly:

hackage-lint: Can be triggered on any MR, normal validate pipeline or nightly build.
              Runs head.hackage with -dlint and a slow-validate bindist

hackage-label-lint: Trigged on MRs with "user-facing" label, runs the slow-validate
                    head.hackage build with -dlint.

nightly-hackage-lint: Runs automatically on nightly pipelines with slow-validate + dlint config.

nightly-hackage-perf: Runs automaticaly on nightly pipelines with release build and eventlogging enabled.

release-hackage-lint: Runs automatically on release pipelines with -dlint on a release bindist.

all)

ci: Run head.hackage jobs on upstream-testing branch rather than master

This change allows less priviledged users to trigger head.hackage jobs
because less permissions are needed to trigger jobs on the
upstream-testing branch, which is not protected.

There is a CI job which updates upstream-testing each hour to the state
of the master branch so it should always be relatively up-to-date.

llvmGen: Fix relaxed ordering

Previously I used LLVM's `unordered` ordering for the C11 `relaxed`
ordering. However, this is wrong and should rather use the LLVM
`monotonic` ordering.

gitlab-ci: Introduce aarch64-linux-llvm job

AArch64/Linux by bootstrapping GHC.

Store RdrName rather than OccName in Holes

In #20472 it was pointed out that you couldn't defer out of scope but
the implementation collapsed a RdrName into an OccName to stuff it into
a Hole. This leads to the error message for a deferred qualified name
dropping the qualification which affects the quality of the error
message.

This commit adds a bit more structure to a hole, so a hole can replace a
RdrName without losing information about what that RdrName was. This is
important when printing error messages.

I also added a test which checks the Template Haskell deferral of out of
scope qualified names works properly.

Fixes #22130

hadrian: Ensure that linker scripts are used when merging objects

In #22527 @rui314 inadvertantly pointed out a glaring bug in Hadrian's
implementation of the object merging rules: unlike the old `make` build
system we utterly failed to pass the needed linker scripts. Fix this.
