primops.

Perf: replace stack checks with assertions in casting primops

There are RESERVED_STACK_WORDS free words (currently 21) on the stack,
so omit the checks.

Suggested by Cheng Shao.

rts/Hash: Don't iterate over chunks if we don't need to free data

When freeing a `HashTable` there is no reason to walk over the hash list
before freeing it if the user has not given us a `dataFreeFun`.

Noticed while looking at #24410.

compiler: add SEQ_CST fence support

In addition to existing Acquire/Release fences, this commit adds
SEQ_CST fence support to GHC, allowing Cmm code to explicitly emit a
fence that enforces total memory ordering. The following logic is
added:

- The MO_SeqCstFence callish MachOp
- The %prim fence_seq_cst() Cmm syntax and the SEQ_CST_FENCE macro in Cmm.h
- MO_SeqCstFence lowering logic in every single GHC codegen backend

testsuite: fix hs_try_putmvar002 for targets without pthread.h

hs_try_putmvar002 includes pthread.h and doesn't work on targets
without this header (e.g. wasm32). It doesn't need to include this
header at all. This was previously unnoticed by wasm CI, though recent
toolchain upgrade brought in upstream changes that completely removes
pthread.h in the single-threaded wasm32-wasi sysroot, therefore we
need to handle that change.

rts: remove redundant rCCCS initialization

This commit removes the redundant logic of initializing each
Capability's rCCCS to CCS_SYSTEM in initProfiling(). Before
initProfiling() is called during RTS startup, each Capability's rCCCS
has already been assigned CCS_SYSTEM when they're first initialized.
