Synopsis
_mm256_srli_si256(__m256i a, const int imm8);
Description
Shift 128-bit lanes in "a" right by "imm8" bytes while shifting in zeros, and store the results in "dst".

tmp := imm8[7:0]
IF tmp > 15
tmp := 16
FI
dst[127:0] := a[127:0] >> (tmp*8)
dst[255:128] := a[255:128] >> (tmp*8)
dst[MAX:256] := 0
