Synopsis
 _mm512_mask_mullo_epi32(__m512i src, __mmask16 k, __m512i a, __m512i b);
Description
Multiply the packed 32-bit integers in "a" and "b", producing intermediate 64-bit integers, and store the low 32 bits of the intermediate integers 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]
		tmp[63:0] := a[i+31:i] * b[i+31:i]
		dst[i+31:i] := tmp[31:0]
	ELSE
		dst[i+31:i] := src[i+31:i]
	FI
ENDFOR
dst[MAX:512] := 0
