* small-sized SmallScannerResult replaces origin ScannerResult in parsing process to reduce the memory pressure.
* ScannerResultVector in parseBinaryExpression is replaced by GC-independent SmallScannerResultVector to reduce the memory overhead (both the performance and memory usage)
* ParseFormalParametersResult holds SyntaxNodeVector instead of NodeVector because each parameter Node is re-generated when it is really necessary (parsing of function call) and we only needs the name and type of each parameter during the pre-parsing
* parser/scanner of parameter parsing is added
* clear up some unnecessary codes such as each friend class annotation in Nodes and NodeVectors

- Remove SourceStringView
- When create AtomicString from StringView, we should make new string data instead of reference StringView
* Reduce size of StringBufferAccessData
* Fix crash in toString of FunctionObject.

- Introduce INIT_STATIC_STRING macro to make adding new static string much easier.
- Introduce AtomicString::initStaticString to append static string to the static string set directly
without lookup for an already existing name.
- Add a number list and remove the dtoa function call for the initialization of string numbers.
- Split the single character initialization to ASCII and Latin1 string part.

- 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.

There is a lot of code duplication for parser and scanner.
Source code duplications can be reduced by templates without sacrificing performance.

Currently the parser is a very large file and hard to maintain. This patch is
the first which splits it into smaller files.
During the move some style fixes are applied. The identifer start
detection is improved as well.
