Previously Hadrian depended implicitly upon whatever `bash` it found in
`PATH`, offerring no way for the user to override. Fix this by detecting
`sh` in `configure` and passing the result to Hadrian.
Fixes #19797.

We now use DsM as the base monad for writing hie files and properly
initialise it from the TcGblEnv.
Before, we would end up reading the interface file from disk for the
module we were currently compiling. The modules iface then ended up in
the EPS causing all sorts of subtle
carnage, including difference in the generated core and haddock emitting
a lot of warnings. With the fix, the
module in the TcGblEnv is set correctly so the lookups happen in the
local name env rather than thinking the identifier comes from an
external package.
Fixes #19693 and #19334

Make is bad, and really slow, and we should just stop using it
outright, or kill hadrian. Let's rather go for hadrian all the
way and phase out make.

The __BSD_VISIBLE and _DARWIN_C_SOURCE macros expose non-POSIX prototypes in
system header files. We should scope these to just the ".c" modules that
actually need them, and avoid defining them in header files used in other C
modules.

This avoids surprises in the non-threaded runtime with blocked signals killing
the process because they're only blocked in the main thread and not in the
ticker thread.

Also some code cleanup, and a fix for an (extant unrelated) missing
<pthread_np.h> include that should hopefully resolve a failure in the
FreeBSD CI build, since it is best to make sure that this MR actually
builds on FreeBSD systems other than mine.
Some unexpected metric changes on FreeBSD (perhaps because CI had been
failing for a while???):

The FreeBSD C <ctype.h> header supports per-thread locales by exporting a
static inline function that references the `_ThreadRuneLocale` thread-local
variable. This means that object files that use e.g. isdigit(3) end up with
TLSGD(19) relocations, and would not load into ghci or the language server.
Here we add support for this type of relocation, for now just on FreeBSD, and
only for external references to thread-specifics defined in already loaded
dynamic modules (primarily libc.so). This is sufficient to resolve the
<ctype.h> issues.
Runtime linking of ".o" files which *define* new thread-specific variables
would be noticeably more difficult, as this would likely require new rtld APIs.

As #19668 showed, there was an /asymptotic/ slow-down in zonking in
GHC 9.0, exposed in test T9198. The bug was actually present in earlier
compilers, but by a fluke didn't actually show up in any of our tests;
but adding Quick Look exposed it.
The bug was that in zonkTyVarOcc we
1. read the meta-tyvar-env variable
2. looked up the variable in the env
3. found a 'miss'
4. looked in the variable, found `Indirect ty`
5. zonked `ty`
6. update the env *gotten from step 1* to map the variable
to its zonked type.
The bug is that we thereby threw away all teh work done in step 4.
In T9198 that made an enormous, indeed asymptotic difference.
The fix is easy: use updTcRef.
I commented in `Note [Sharing when zonking to Type]`

this causes *significant* slowdown on macOS as the linker ends
up looking through all the paths. Slowdown can be as bad as
100% or more.

this prevents the testlib/driver to be overly noisy, and will also
kill some noise produiced by the aarch64-darwin cc (for now).
Fixing sysctl, will allow us to run the test's properly in a nix-shell

Previously Unarise would happily project lifted and unlifted fields
to lifted slots. This broke horribly in #19645, where a ByteArray# was
passed in a lifted slot and consequently entered. The simplest way to
fix this is what I've done here, distinguishing between lifted and
unlifted slots in unarise.
However, one can imagine more clever solutions, where we coerce the
binder to the correct levity with respect to the sum's tag. I doubt that
this would be worth the effort.
Fixes #19645.

There were two different issues:
1. integralFractionalLit needed to be passed an already negated value. (T19680)
2. negateFractionalLit did not actually negate the argument, only
flipped the negation flag. (T19680A)
Fixes #19680
