Synopsis
 _mm512_mask_max_epi32(__m512i src, __mmask16 k, __m512i a, __m512i b);
Description
Compare packed signed 32-bit integers in "a" and "b", and store packed maximum values in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 15
	i := j*32
	IF k[j]
		dst[i+31:i] := MAX(a[i+31:i], b[i+31:i])
	ELSE
		dst[i+31:i] := src[i+31:i]
	FI
ENDFOR
dst[MAX:512] := 0
