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.

rts/m32: Fix sanity checking

read-only. Fix this.
