Please add support for EXTENDED_ARG in jumps about bytecode HOT 2 CLOSED

            if jump > 0xFFFF:
                raise NotImplementedError("Extended jumps not implemented")

    /* XXX: This is an awful hack that could hurt performance, but
        on the bright side it should work until we come up
        with a better solution.

        The issue is that in the first loop blocksize() is called
        which calls instrsize() which requires i_oparg be set
        appropriately.          There is a bootstrap problem because
        i_oparg is calculated in the second loop above.

        So we loop until we stop seeing new EXTENDED_ARGs.
        The only EXTENDED_ARGs that could be popping up are
        ones in jump instructions.  So this should converge
        fairly quickly.
