[JSC] Use UCPURegister argument to remove zero extension in JIT code
https://bugs.webkit.org/show_bug.cgi?id=228625

Reviewed by Robin Morisset.

Yarr JIT code emits zeroExtend32ToWord for some arguments, but this is not necessary if
argument is defined as UCPURegister. In that case, caller guarantees that top 32bits are
cleared.
