* 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

- 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.
