Synopsis
 _mm512_maskz_fnmadd_ph(__mmask32 k, __m512h a, __m512h b, __m512h c);
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" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
FOR j := 0 to 31
	IF k[j]
		dst.fp16[j] := -(a.fp16[j] * b.fp16[j]) + c.fp16[j]
	ELSE
		dst.fp16[j] := 0
	FI
ENDFOR
dst[MAX:512] := 0
