        * config/rs6000/rs6000-cpus.def (OTHER_P9_VECTOR_MASKS): Define
        masks of options that should be turned off if the VSX vector
        options are turned off.
        (OTHER_P8_VECTOR_MASKS): Likewise.
        (OTHER_VSX_VECTOR_MASKS): Likewise.
        * config/rs6000/rs6000.c (rs6000_option_override_internal): Call

        like -mvsx.
        (rs6000_incompatible_switch): New function to disallow turning on
        other vector options if -mno-vsx, -mno-power8-vector, or
