* Optimize ObjectStructurePropertyDescriptor * Don't initialize inline storage of VectorWithInlineStorage * Add Object::setPrototypeForIntrinsicObjectCreation for fast initialize * Add ArrayObject::ArrayObject(ExecutionState& state, const uint64_t& size) for fast initialize * Store stack-limit instead of stack-base * Reduce size of ExecutionState * Add fast version of Object::ownPropertyKeys for optimize Object.keys * Add ValueVectorWithInlineStorage * Remove some compiler warnings Signed-off-by: seonghyun kim <sh8281.kim@samsung.com>
