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.

Addresses #25242

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.

Fixes #25274
