Synopsis
 _mm256_mul_epi32(__m256i a, __m256i b);
Description
Multiply the low signed 32-bit integers from each packed 64-bit element in "a" and "b", and store the signed 64-bit results in "dst".
Operation
FOR j := 0 to 3
	i := j*64
	dst[i+63:i] := SignExtend64(a[i+31:i]) * SignExtend64(b[i+31:i])
ENDFOR
dst[MAX:256] := 0
