[JSC] Atomize 2-character substrings
https://bugs.webkit.org/show_bug.cgi?id=259675
rdar://113184158
Reviewed by Mark Lam.
This imports V8's heuristics: V8 atomize 2-character substrings because they
are too
frequently used as a key of dictionary: because of code minifiers. This patch
adopts
this change into our jsSubstringOfResolved.
