[JSC] Add global replace caching
https://bugs.webkit.org/show_bug.cgi?id=257826
rdar://110417641
Reviewed by Michael Saboff.
This patch adds String.replace(/regexp-global/g, func) result cache, which is
in the same fashion to V8's cache.
We cache the result only when the subject string length is >= 0x1000, aligned
to V8's behavior.
This cache is cleared on every GC, so it does not affect on memory usage in
practice: once GC happens, everything gets cleared,
so it is not retaining things.
* JSTests/stress/v8-regexp-results-cache.js: Added.
* JSTests/stress/v8-string-replace-cache.js: Added.
