* treat variable in catch() as let
* add lexical environment record data into global environment for saving global permanently
* re-implement variable access bytecode generation
* re-implement class initialize operation
* re-implement global variable access bytecode for support lexcial variables in global
* fix bugs related with per-iteration lexical environment in for-statement

- 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.

* in most cases, parsing and bytecode generation process runs sequentially
* parsing error throws SyntaxError exception inside sandbox and this exception will be catched by the sandbox
* clear up some complicated code

2. alloc esprima::Error as Non-GC type.
- it can be thrown. but, bdwgc can not see try-catch variable area.
