Synopsis
 _mm_maskz_unpackhi_epi64(__mmask8 k, __m128i a, __m128i b);
Description
Unpack and interleave 64-bit integers from the high half of "a" and "b", and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation

	RETURN dst[127:0]
}

FOR j := 0 to 1

	IF k[j]
		dst[i+63:i] := tmp_dst[i+63:i]
	ELSE
		dst[i+63:i] := 0
