* 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
rs6000_disable_incompatible_switches to validate no type switches
like -mvsx.
(rs6000_incompatible_switch): New function to disallow turning on
other vector options if -mno-vsx, -mno-power8-vector, or
-mno-power9-vector are specified.
