* 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.

* Implement RuntimeICUBinder
- ICU has verison name on its symbol name like u_tolower_XX.
but, we need to use escargot on various platform(without re-compile)
thus, I implement this library

- there is an issue with -0 in builtin ceil function

The function had a wrong behaviour expecting `this` value to be a RegExp Object.
However as the standard says `this` value should be an Object, and its `source` and `pattern` values' `toString()`s should be returned in a form of `/<source>/<flags>`.

* Don't use memcpy on PointerValue objects
Class `PointerValue` and its descendants are dynamic classes, their
instances have a vtable pointer. C functions like `memcpy` know
nothing about C++ classes and object memory layouts, so using
C-style memory access to C++ objects with vtable pointers makes the
compiler complain.
This patch replaces `memcpy` with a more C++-ish approach.
