- closes: #25331
This is the last step in the project plan described in #25331. This
commit:
- adds bitcast operands for x86_64, LLVM, aarch64
- For PPC and i386 we resort to using the cmm implementations
- renames conversion MachOps from Conv to Round|Truncate

Some functions in StgToByteCode were filtering out void arguments.
However, StgToByteCode is called after unarisation: the void arguments
should have been removed earlier.
Instead of filtering out, we assert that the args are non-void.

`layoutNativeCall` was always called with a `primRepCmmType platform`
callback. Hence we can put it inside of `layoutNativeCall` rather than
repeat it.

This patch makes the STG->Cmm backend avoid saving foreign call target
to local when there are no caller-save GlobalRegs.
Since 321941a8ebe25192cdeece723e1058f2f47809ea, when we lower a
foreign call, we unconditionally save the foreign call target to a
temporary local first, then rely on cmmSink to clean it up later,
which only happens with -fcmm-sink (implied by -O) and not in
unoptimized code.
And this is troublesome for the wasm backend NCG, which needs to infer
a foreign call target symbol's type signature from the Cmm call site.
Previously, the NCG has been emitting incorrect type signatures for
unoptimized code, which happens to work with `wasm-ld` most of the
time, but this is never future-proof against upstream toolchain
updates, and it causes horrible breakages when LTO objects are
included in linker input. Hence this patch.
