1. not every binding is mutable in strict mode

Browse source 
- add m_isExplicitlyDeclaredOrParameterName into name info in ASTScopeContext
  - add m_isMutable into IdentifierRecord struct
  - add ThrowStaticExcpetion opcode in indexed-mode
  - add throw exception code in storeByName operation
2. when evaluate delete operation on member variable, must evaluate toString operation once for name even if exception throws
3. in strict mode, Decimals with leading zero literals are not allowed
