Synopsis
 _mm_mask_move_sd(__m128d src, __mmask8 k, __m128d a, __m128d b);
Description
Move the lower double-precision (64-bit) floating-point element from "b" to the lower element of "dst" using writemask "k" (the element is copied from "src" when mask bit 0 is not set), and copy the upper element from "a" to the upper element of "dst".
Operation
IF k[0]
	dst[63:0] := b[63:0]
ELSE
	dst[63:0] := src[63:0]
FI
dst[127:64] := a[127:64]
dst[MAX:128] := 0
