This improves the fix committed at revision 199683 adding the
following new target specific combine rules:
1) fold (v4i32: vselect <0,0,-1,-1>, A, B) ->
(v4i32 (bitcast (movsd (v2i64 (bitcast A)), (v2i64 (bitcast B))) ))
2) fold (v4f32: vselect <0,0,-1,-1>, A, B) ->
(v4f32 (bitcast (movsd (v2f64 (bitcast A)), (v2f64 (bitcast B))) ))
3) fold (v4i32: vselect <-1,-1,0,0>, A, B) ->
(v4i32 (bitcast (movsd (v2i64 (bitcast B)), (v2i64 (bitcast A))) ))
4) fold (v4f32: vselect <-1,-1,0,0>, A, B) ->
(v4f32 (bitcast (movsd (v2i64 (bitcast B)), (v2i64 (bitcast A))) ))
