aarch64: Reorder FMV feature priorities

Some higher priority FMV features were dependent subsets of lower
priority features.  Fix this, using the new priorities specified in
https://github.com/ARM-software/acle/pull/279.

gcc/ChangeLog:

	* config/aarch64/aarch64-option-extensions.def: Reorder FMV entries.

gcc/testsuite/ChangeLog:

	* gcc.target/aarch64/cpunative/native_cpu_21.c: Reorder features.
	* gcc.target/aarch64/cpunative/native_cpu_22.c: Ditto.
