Improve performance (#337)

Browse source 
* 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
