        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.
