the statement node infos should be constructed in the beginning of their parsing functions.

but I don't want to add extra bytecodes for this.

* When there is arrow function on class ctor, we should use heap-allocated lex env for class ctor.
because we need to compute this variable on run-time
* when there is super expression with computed case, we should load this binding first for testing binding

* 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
