Separate the new FP16 instructions backported from Armv8.4-a to Armv8.2-a into a new flag order to distinguish them from the rest of the already existing optional FP16 instructions in Armv8.2-a.
The new flag "+fp16fml" is available from Armv8.2-a and implies +fp16 and is mandatory
from Armv8.4-a.
gas/
* config/tc-arm.c (arm_ext_fp16_fml, fp16fml): New.
