Synopsis
 _mm_mask_set1_epi64(__m128i src, __mmask8 k, __int64 a);
Description
Broadcast 64-bit integer "a" to all elements of "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 1
	i := j*64
	IF k[j]
		dst[i+63:i] := a[63:0]
	ELSE
		dst[i+63:i] := src[i+63:i]
	FI
ENDFOR
