Synopsis
 _mm512_fnmadd_round_ph(__m512h a, __m512h b, __m512h c, const int rounding);
Description
Multiply packed half-precision (16-bit) floating-point elements in "a" and "b", add the negated intermediate result to packed elements in "c", and store the results in "dst". [round_note]
Operation
FOR j := 0 to 31
	dst.fp16[j] := -(a.fp16[j] * b.fp16[j]) + c.fp16[j]
ENDFOR
dst[MAX:512] := 0
