VPSHRDD - Packed SHift Right Double Dword

VPSHRDD xmm1{k1}{z}, xmm2, xmm3/m128/m32bcst, imm8    (V5+VBMI2+VL
__m128i _mm_shrdi_epi32(__m128i a, __m128i b, int imm8)
__m128i _mm_mask_shrdi_epi32(__m128i s, __mmask8 k, __m128i a, __m128i b, int imm8)
__m128i _mm_maskz_shrdi_epi32(__mmask8 k, __m128i a, __m128i b, int imm8)

For each DWORD, (1) is shifted to the right by the number of bits specified in imm8 bit 4:0. Lower bits of (2) are copied to the emptied upper bits. The result is stored in (3).
VPSHRDD ymm1{k1}{z}, ymm2, ymm3/m256/m32bcst, imm8    (V5+VBMI2+VL
__m256i _mm256_shrdi_epi32(__m256i a, __m256i b, int imm8)
__m256i _mm256_mask_shrdi_epi32(__m256i s, __mmask8 k, __m256i a, __m256i b, int imm8)
__m256i _mm256_maskz_shrdi_epi32(__mmask8 k, __m256i a, __m256i b, int imm8)

For each DWORD, (1) is shifted to the right by the number of bits specified in imm8 bit 4:0. Lower bits of (2) are copied to the emptied upper bits. The result is stored in (3).
VPSHRDD zmm1{k1}{z}, zmm2, zmm3/m512/m32bcst, imm8    (V5+VBMI2
__m512i _mm512_shrdi_epi32(__m512i a, __m512i b, int imm8)
__m512i _mm512_mask_shrdi_epi32(__m512i s, __mmask16 k, __m512i a, __m512i b, int imm8)
__m512i _mm512_maskz_shrdi_epi32(__mmask16 k, __m512i a, __m512i b, int imm8)

For each DWORD, (1) is shifted to the right by the number of bits specified in imm8 bit 4:0. Lower bits of (2) are copied to the emptied upper bits. The result is stored in (3).
