VPTESTMW - Packed TEST Mask Word

VPTESTMW k1{k2}, xmm2, xmm3/m128    (V5+BW+VL
__mmask8 _mm_test_epi16_mask(__m128i a, __m128i b)
__mmask8 _mm_mask_test_epi16_mask(__mmask8 k2, __m128i a, __m128i b)

For each WORD, calculate bitwise (1) & (2), if any bit of the result is 1, 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.
VPTESTMW k1{k2}, ymm2, ymm3/m256    (V5+BW+VL
__mmask16 _mm256_test_epi16_mask(__m256i a, __m256i b)
__mmask16 _mm256_mask_test_epi16_mask(__mmask16 k2, __m256i a, __m256i b)

For each WORD, calculate bitwise (1) & (2), if any bit of the result is 1, 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.

__mmask32 _mm512_test_epi16_mask(__m512i a, __m512i b)
__mmask32 _mm512_mask_test_epi16_mask(__mmask32 k2, __m512i a, __m512i b)

For each WORD, calculate bitwise (1) & (2), if any bit of the result is 1, 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.
