SpecConstr: Introduce a separate argument limit for forced specs.

We used to put no limit at all on specializations forced via the SPEC
argument. This isn't always reasonable so we introduce a very high limit
that applies to forced specializations, a flag to control it, and we now
emit a warning if we fail a specialization because we exceed the
warning.

Fixes #25197

ghc-experimental: Expose primops and ghc extensions via GHC.PrimOps

This will be the new place for functions that would have gone into
GHC.Exts in the past but are not stable enough to do so now.

RTS: cleanup timerfd file descriptors after a fork (#25280)

When we init a timerfd-based ticker, we should be careful to cleanup the
old file descriptors (e.g. after a fork).

determinism: Deterministic MonadGetUnique LlvmM

Update LlvmM to thread a unique deterministic supply (using UniqDSMT),
and use it in the MonadGetUnique instance.

This makes uniques sampled from LlvmM deterministic, which guarantees
object determinism with -fllvm.

for testing.

configure: Allow happy-2.0.2

happy-2.0.2 can be used to compile GHC.

happy-2.0 and 2.0.1 have bugs which make it unsuitable to use.

The version bound is now == 1.20.* || >= 2.0.2 && < 2.1

Fixes #25276

Fix registerArch for riscv64

The register allocator doesn't support vector registers on riscv64,
therefore advertise as NoVectors.

Fixes #25314

riscv: Avoid using csrr instruction to test for vector registers

The csrr instruction isn't allowed in qemu user-mode, and raises an
illegal instruction error when it is encountered.

Therefore for now, we just hard-code that there is no support for vector
registers since the rest of the compiler doesn't support vector
registers for riscv.

Fixes #25312

testsuite/perf: Report better error message on malformed note

Previously a malformed perf note resulted in very poor errors.
Here we slight improve this situation.

ci: Add nightly & release ubuntu-22.04 jobs

This adds build of bindists on ubuntu-22.04 on nightly and release
pipelines.

We also update ghcup-metadata to provide ubuntu-22.04 bindists on
ubuntu-22.04.

haddock: Bump binary interface version to 46.

This allows haddock to give good error messages when being used on mismatched interface files.

We bump to 46 since GHC 9.12 uses version 45: https://gitlab.haskell.org/ghc/ghc/-/commit/362afd632032ee8f174690c3ffe0015076b83ce6

This should have been done in e4ac1b0d281b85a0144d1ef6f84a1df00e236052 but was overlooked.

Change versionig of ghc-experimental to follow ghc versions.

Just like ghc-internal it will now use the @ProjectVersionForLib@ macro for versioning.
This means for ghc=9.10.1, ghc-experimental's version will be 9.1001.0 and so on.

This fixes #25289

Exception rethrowing

Basic changes:

* Change `catch` function to propagate exceptions using the
  WhileHandling mechanism.
* Introduce `catchNoPropagate`, which does the same as before, but
  passes an exception which can be rethrown.
* Introduce `rethrowIO` combinator, which rethrows an exception with a
  context and doesn't add a new backtrace.
* Introduce `tryWithContext` for a variant of `try` which can rethrow
  the exception with it's original context.
* onException is modified to rethrow the original error rather than
  creating a new callstack.
* Functions which rethrow in GHC.Internal.IO.Handle.FD,
  GHC.Internal.IO.Handle.Internals, GHC.Internal.IO.Handle.Text, and
  GHC.Internal.System.IO.Error are modified to not add a new callstack.

Implements CLC proposal#202 <https://github.com/haskell/core-libraries-committee/issues/202>

Refactored BooleanFormula to be in line with TTG (#21592)

This means two things:
  We moved the definition of BooleanFormula to L.H.S.BooleanFormula
  We went from 'BooleanFormula a' with the datacon (Var a) to
  BooleanFormula p, where the datacon is instead (Var (LIdp p)).
And a lot of churn to make everything compile. We will see if the test cases
succeed. I assume not, as I have changed data types without touching the
test cases...
