Synopsis
 _mm256_mask_cvtepu16_epi64(__m256i src, __mmask8 k, __m128i a);
Description
Zero extend packed unsigned 16-bit integers in the low 8 bytes of "a" to packed 64-bit integers, and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 3
	i := 64*j
	l := 16*j
	IF k[j]
		dst[i+63:i] := ZeroExtend64(a[l+15:l])
	ELSE
		dst[i+63:i] := src[i+63:i]
	FI
ENDFOR
dst[MAX:256] := 0
