Synopsis
 _mm512_maskz_inserti64x2(__mmask8 k, __m512i a, __m128i b, int imm8);
Description
Copy "a" to "tmp", then insert 128 bits (composed of 2 packed 64-bit integers) from "b" into "tmp" at the location specified by "imm8". Store "tmp" to "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
tmp[511:0] := a[511:0]
CASE (imm8[1:0]) OF
0: tmp[127:0] := b[127:0]
1: tmp[255:128] := b[127:0]
2: tmp[383:256] := b[127:0]
3: tmp[511:384] := b[127:0]
