================
Comment at: lib/Transforms/Vectorize/LoopVectorize.cpp:5054
   // single loop.
   DT->addNewBlock(LoopVectorBody, LoopVectorPreHeader);
 
----------------
Should this be 
```
DT->addNewBlock(LI->getLoopFor(LoopVectorBody)->getHeader(), LoopVectorPreHeader);
```
as long as we're at it?
