* Optmize String.protype.split function.
when separator comes to RegExpObject split function, we have to call @@split function when there is a @@split function.
old one is correct implementation but performance is bad...
but we already have optmized split function with RegExp in builtinStringSplit.
I make to use old one when if user didn't defined own @@split function.
RegExp test score is changed from 57 to 280 in my computer.
* Make Value::isCallable inline-able.
* Make to use shared data among {Get,Set}GlobalVariable. this may reduce usage & improve performance

- Store lexcial block informantion in InterpretedCodeBlock.
- If lexcial block has no lexcial variables, we should collapse the block.
- If there is no heap-allocated variables in lexcial environment, we can skip allocation of the environment.
- Implement Indexed storage for lexcial environment.
- Allocate lexcial variables in function stack storage if possible.
