	PR target/67211
	* 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.
