VPCMPD - Packed CoMPare Dword (imm8=1)

VPCMPD k1{k2}, xmm2, xmm3/m128/m32bcst, 1    (V5+VL
__mmask8 _mm_cmplt_epi32_mask(__m128i a, __m128i b)
__mmask8 _mm_mask_cmplt_epi32_mask(__mmask8 k2, __m128i a, __m128i b)

For each signed DWORD, if (1) < (2) set 1, else set 0, to the corresponding bit of (3).
If k2 bit is 0, the comparison is not done and the corresponding bit of (3) is set to zero. Upper bits of (3) are zero cleared.
VPCMPD k1{k2}, ymm2, ymm3/m256/m32bcst, 1    (V5+VL
__mmask8 _mm256_cmplt_epi32_mask(__m256i a, __m256i b)
__mmask8 _mm256_mask_cmplt_epi32_mask(__mmask8 k2, __m256i a, __m256i b)

For each signed DWORD, if (1) < (2) set 1, else set 0, to the corresponding bit of (3).
If k2 bit is 0, the comparison is not done and the corresponding bit of (3) is set to zero. Upper bits of (3) are zero cleared.

__mmask16 _mm512_mask_cmplt_epi32_mask(__mmask16 k2, __m512i a, __m512i b)

For each signed DWORD, if (1) < (2) set 1, else set 0, to the corresponding bit of (3).
If k2 bit is 0, the comparison is not done and the corresponding bit of (3) is set to zero. Upper bits of (3) are zero cleared.
