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.

Bump LLVM upper bound to allow LLVM 19

Also bumps the ci-images commit so that the deb12 images uses LLVM 19
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

ghc-internal: Drop GHC.Internal.Data.Enum

This module consists only of reexports and consequently there is no
reason for it to exist.

base: Introduce Data.Bounded

As proposed in [CLC#208] but unfortunately `Data.Enum` was already
incorrectly introduced in the `ghc-internal` refactor.
