[ARM][AArch64] Add feature +fp16fml
Armv8.4-A adds a few FP16 instructions that can optionally be implemented
in CPUs of Armv8.2-A and above.
This patch adds a feature to clang to permit selection of these
instructions. This interacts with the +fp16 option as follows:
Prior to Armv8.4-A:
*) +fp16fml implies +fp16
*) +nofp16 implies +nofp16fml
From Armv8.4-A:
*) The above conditions apply, additionally: +fp16 implies +fp16fml
Patch by Bernard Ogden.
