Synopsis
 _mm512_mask_cvtepi64_pd(__m512d src, __mmask8 k, __m512i a);
Description
Convert packed signed 64-bit integers in "a" to packed double-precision (64-bit) floating-point elements, 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 7
	i := j*64
	IF k[j]
		dst[i+63:i] := Convert_Int64_To_FP64(a[i+63:i])
	ELSE
		dst[i+63:i] := src[i+63:i]
	FI
ENDFOR
dst[MAX:512] := 0
