* Object, Array, Environment record internal space should use 32bit addressing on 64bit
* Rename SmallValue to EncodedValue.
* Implement EncodedSmallValue for using 32bit address on 64bit
* Implement special vectors for EncodedSmallValue.
- we need these special vector. because when push_back or inserting the value what we want to insert
can be removed by GC because the parameter type is 32bit(EncodedSmallValue).
* Update GCutil for 32bit addressing on 64bit

* 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); }`
