Correct.  There are generic vectorizer changes that would need to be 
ported over to that branch to make those tests pass.  I looked at this a 
few times and ultimately gave up in the rats nest of inter-dependent 
patches in the vectorizer.


Given the lifetime of that branch is likely nearing its end, I don't 
think there's much value left in trying to port those changes over. Any 
such effort would likely be better spent nailing down issues on the trunk.
