Synopsis
 _mm512_testn_epi32_mask(__m512i a, __m512i b);
Description
Compute the bitwise NAND of packed 32-bit integers in "a" and "b", producing intermediate 32-bit values, and set the corresponding bit in result mask "k" if the intermediate value is zero.
Operation
FOR j := 0 to 15
	i := j*32
	k[j] := ((a[i+31:i] AND b[i+31:i]) == 0) ? 1 : 0
ENDFOR
k[MAX:16] := 0
