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.
