VPTESTNMB - Packed TEST Nand Mask Byte

VPTESTNMB k1{k2}, xmm2, xmm3/m128    (V5+BW+VL
__mmask16 _mm_testn_epi8_mask(__m128i a, __m128i b)
__mmask16 _mm_mask_testn_epi8_mask(__mmask16 k2, __m128i a, __m128i b)

For each BYTE calculate bitwise (1) & (2), if all the bits of the result are 0, set 1, else set 0, to the corresponding bit of (3).
If k2 bit is 0, the calculation is not done and the corresponding bit of (3) is set to zero. Upper bits of (3) are zero cleared.
VPTESTNMB k1{k2}, ymm2, ymm3/m256    (V5+BW+VL
__mmask32 _mm256_testn_epi8_mask(__m256i a, __m256i b)
__mmask32 _mm256_mask_testn_epi8_mask(__mmask32 k2, __m256i a, __m256i b)

For each BYTE calculate bitwise (1) & (2), if all the bits of the result are 0, set 1, else set 0, to the corresponding bit of (3).
If k2 bit is 0, the calculation is not done and the corresponding bit of (3) is set to zero. Upper bits of (3) are zero cleared.

__mmask64 _mm512_mask_testn_epi8_mask(__mmask64 k2, __m512i a, __m512i b)

For each BYTE calculate bitwise (1) & (2), if all the bits of the result are 0, set 1, else set 0, to the corresponding bit of (3).
If k2 bit is 0, the calculation is not done and the corresponding bit of (3) is set to zero. Upper bits of (3) are zero cleared.
