* Many JS Frameworks or librarys use `function.apply(<any>, arguments)` pattern.
but this statement generate arguments object. generateing arguments object is very expensive.
we can optimize simple cases like `function() { fn.apply(this, arguments); }`
* Merge many ByteCode opcodes into CallFunctionComplexCase.
* Do gc when allocate large ArrayBuferObject

* Compress CompressibleStrings on GC reclaim end event
- if there is reference about data of CompressibleString on stack, we should give up compressing.
we don't need to search heap space because I redesigned StringView
(we should not store string buffer data on heap without owner)
* Redesign StringView
- Don't save string buffer address as its member. because buffer of CompressibleString can be deleted
- If we don't save string buffer address on StringView, parser performance may dropped.
becuase parser access string data a lot.
so I introduce ParserStringView. it saves buffer address. we should ParserStringView on parser only.
we can save string buffer address while parsing. because GC is disabled while parsing.
* Enable CompressibleString always
* Implement cache of RegExpOptionStrings
* Implement finding system locale function on RuntimeICUBinder avoiding call uloc_getDefault.
