Synopsis
 _mm512_mask_fnmsub_ps(__m512 a, __mmask16 k, __m512 b, __m512 c);
Description
Multiply packed single-precision (32-bit) floating-point elements in "a" and "b", subtract packed elements in "c" from the negated intermediate result, and store the results in "dst" using writemask "k" (elements are copied from "a" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 15
	i := j*32
	IF k[j]
		dst[i+31:i] := -(a[i+31:i] * b[i+31:i]) - c[i+31:i]
	ELSE
		dst[i+31:i] := a[i+31:i]
	FI
ENDFOR	
dst[MAX:512] := 0
