  Some architecture features have been combined under a single command
line flag, but have been assigned multiple FMV feature names with the
command line flag name enabling only a subset of these features in
the FMV specification.  Remove the unsupported FMV subfeatures, and
rename the remaining features with the corresponding command line flag
names.  This change is also proposed in the specification:
https://github.com/ARM-software/acle/pull/315

gcc/ChangeLog:

	* config/aarch64/aarch64-option-extensions.def:
	Combine "memtag2" into "memtag", "ssbs2" into "ssbs", and
	"ls64_v and ls64_accdata" into "ls64".
