Optimize runtime performance

Browse source 
* 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
