            Ensure all values are correctly tagged in the registerfile

            This patch makes sure that all JSCell pointers written to
            the registerfile are correctly tagged as JSCells, and replaces
            raw int usage with the immediate representation.
    
            For performance, register pressure, and general saneness reasons
            I've added abstractions for reading and writing the tag
            and payload of integer registers directly for the JSVALUE64
            encoding.
