ARM vectorized fp16 support
...fails to automatically generate fused-multiply-add instructions
for c += a * b. I'm wondering whether I did something wrong, if not,
is it a missing feature that will be supported later? (I know there're
fp16 FMLA intrinsics though)
Test programs and outputs,
$ clang -O3 -march=armv8.2-a+fp16fml -ffast-math -S -o- vfp32.c
test_vfma_lane_f16: // @test_vfma_lane_f16
fmla v2.4s, v1.4s, v0.4s // fp32 is GOOD
mov v0.16b, v2.16b
ret
$ cat vfp32.c
#include <arm_neon.h>
