[JSC] Add small-sized fast fill before memset in operationMemoryFill
https://bugs.webkit.org/show_bug.cgi?id=321850
rdar://185002028
Reviewed by Justin Michaud.
As the same to 319202@main, we do inlined small-sized memset in
operationMemoryFill function before calling memset.
We do not do the same to MemoryCopy about paired approach as using FPR
etc. would be costly in filling case than copying case.
