for runnung octane, we should make 1.05M copies of FunctionEnvironmentRecordOnHeap.
but almost copies(0.84M) of FunctionEnvironmentRecordOnHeap use under 5 heapStorage.
If we inline heapStorage, we can reduce count of GC_MALLOC.

* 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

* 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.

- 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.
