Optimize execution speed (#374)

Browse source 
* Set ALWAYS_INLINE flag for SmallValue <-> Value convertor function
* Implement ScriptGeneratorFunctionObject for remove if-statement in FunctionCall
* Remove calling Object::call in CallFunction, CallFunctionWithReceiver opcode
* if function uses global variable only, we should not use heap env for the function
* Don't use bitfield for ExecutionState::m_inStrictMode because we have only one flag at there.
* Remove useless submodules (test262-master, test262-harness)
