Synopsis
 _mm256_mask_broadcastsd_pd(__m256d src, __mmask8 k, __m128d a);
Description
Broadcast the low double-precision (64-bit) floating-point element from "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 3
	i := j*64
	IF k[j]
		dst[i+63:i] := a[63:0]
	ELSE
		dst[i+63:i] := src[i+63:i]
	FI
ENDFOR
dst[MAX:256] := 0
