Added ReferenceError for this inside derived class' constructor

I've added the support for throwing ReferenceError inside a derived class' constructor.  There is one ugliness here, which is having to remember whether a given constructor is for a derived class or not.  I don't think we can deduce this from prototype or constructor as far as I read the spec so I'm introducing a yet another private property name to store this information on the constructor object.

Now I need to figure out how to pass an argument to eval operator so that every access to this inside an eval operator in a derived class' constructor would check the extra register allocated in BytecodeGenerator for the constructor.
