Synopsis
 _mm512_shrdi_epi32(__m512i a, __m512i b, int imm8);
Description
Concatenate packed 32-bit integers in "b" and "a" producing an intermediate 64-bit result. Shift the result right by "imm8" bits, and store the lower 32-bits in "dst".
Operation
FOR j := 0 to 15
	i := j*32
	dst[i+31:i] := ((b[i+31:i] << 32)[63:0] | a[i+31:i]) >> imm8[4:0]
ENDFOR
dst[MAX:512] := 0
