aarch64: Add new +flagm2 flag
GCC does not currently emit the axflag or xaflag instructions, so this
primarily affects the flags passed through to the assembler.
gcc/ChangeLog:
* config/aarch64/aarch64-arches.def (V8_5A): Add FLAGM2.
* config/aarch64/aarch64-option-extensions.def (FLAGM2): New flag.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/cpunative/native_cpu_21.c: Add flagm2 to
expected feature string instead of flagm.
* gcc.target/aarch64/cpunative/native_cpu_22.c: Ditto.
