Optimize constant localloc on x64 (#53755)

* Optimize constant localloc on x64

Avoid popping off the outgoing arg space just to push it back later,
for constant size localloc. This typically removes two `sub rsp`
instructions per case, although we don't do the `push 0` "optimization",
so sometimes there are more instructions removed.

* Fix clang build error
