Synopsis
 _mm256_fmsub_ph(__m256h a, __m256h b, __m256h c);
Description
Multiply packed half-precision (16-bit) floating-point elements in "a" and "b", subtract packed elements in "c" from the intermediate result, and store the results in "dst".
Operation
FOR j := 0 to 15
	dst.fp16[j] := (a.fp16[j] * b.fp16[j]) - c.fp16[j]
ENDFOR
dst[MAX:256] := 0
