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.

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

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

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.

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>

driver: fix runWorkerLimit on wasm
This commit fixes link-time unresolved symbol errors for sem_open etc
on wasm, by making runWorkerLimit always behave single-threaded. This
avoids introducing the jobserver logic into the final wasm module and
thus avoids referencing the posix semaphore symbols.

Parallelize getRootSummary computations in dep analysis downsweep
This reuses the upsweep step's infrastructure to process batches of
modules in parallel.
I benchmarked this by running `ghc -M` on two sets of 10,000 modules;
one with a linear dependency chain and the other with a binary tree.
Comparing different values for the number of modules per thread
suggested an optimum at `length targets `div` (n_cap * 2)`, with results
similar to this one (6 cores, 12 threads):
```
Benchmark 1: linear 1 jobs
Time (mean ± σ): 1.775 s ± 0.026 s [User: 1.377 s, System: 0.399 s]
Range (min … max): 1.757 s … 1.793 s 2 runs
Benchmark 2: linear 6 jobs
Time (mean ± σ): 876.2 ms ± 20.9 ms [User: 1833.2 ms, System: 518.6 ms]
Range (min … max): 856.2 ms … 898.0 ms 3 runs
Benchmark 3: linear 12 jobs
Time (mean ± σ): 793.5 ms ± 23.2 ms [User: 2318.9 ms, System: 718.6 ms]
Range (min … max): 771.9 ms … 818.0 ms 3 runs
```
Results don't differ much when the batch size is reduced to a quarter
of that, but there's significant thread scheduling overhead for a size
of 1:
```
Benchmark 1: linear 1 jobs
Time (mean ± σ): 2.611 s ± 0.029 s [User: 2.851 s, System: 0.783 s]
Range (min … max): 2.591 s … 2.632 s 2 runs
Benchmark 2: linear 6 jobs
Time (mean ± σ): 1.189 s ± 0.007 s [User: 2.707 s, System: 1.103 s]
Range (min … max): 1.184 s … 1.194 s 2 runs
Benchmark 3: linear 12 jobs
Time (mean ± σ): 1.097 s ± 0.006 s [User: 2.938 s, System: 1.300 s]
Range (min … max): 1.093 s … 1.101 s 2 runs
```
Larger batches also slightly worsen performance.
