This revision is now accepted and ready to land.

This looks fine, with a minor comment.



================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:2620
   // Determine the number of scalars we need to generate for each unroll
   // iteration. If EntryVal is uniform, we only need to generate the first
   // lane. Otherwise, we generate all VF values.
----------------
Update comment as EntryVal is no longer checked? In fact, it need not be passed in.
