<pre>Now that vector versions of the *.overflow intrinsics are supported we need to
add vectorization support.
For instance, in SLP BoUpSLP::canMapToVector can't handle the return struct
type:
{i32, i1} @llvm.sadd.with.overflow.i32(i32 %a, i32 %b)
to
{<4 x i32>, <4 x i1>} @llvm.sadd.with.overflow.v4i32(<4 x i32> %a, <4 x i32>
%b)
The LV has similar issues.</pre>
