        * config/rs6000/rs6000-cpus.def (ISA_2_7_MASKS_SERVER): Set
        -mefficient-unaligned-vsx on ISA 2.7.

        * config/rs6000/rs6000.opt (-mefficient-unaligned-vsx): Convert
        option to a masked option.

        * config/rs6000/rs6000.c (rs6000_option_override_internal): Rework
        logic for -mefficient-unaligned-vsx so that it is set via an arch
        ISA option, instead of being set if -mtune=power8 is set. Move
        -mefficient-unaligned-vsx and -mallow-movmisalign handling to be
        near other default option handling.
