* d10v-tdep.c (d10v_read_sp, d10v_read_fp): Add prototype.
        (d10v_register_virtual_type): Make $fp and $sp be pointer to data.
        (d10v_integer_to_address): Rewrite.
        (d10v_frame_init_saved_regs): When reading fp and sp registers use
        the d10v specific functions which take care of converting to the
        correct space.
