[PATCH] D50480: [LV] Vectorizing loops of arbitrary trip count without remainder under opt for size

[Ayal Zaks via Phabricator via llvm-commits]

Ayal updated this revision to Diff 161965.
Ayal added a comment.

Addressing review comments, rebased, added a couple of asserts.

Reverted to use the original ICmpULE extended opcode instead of detached ICmpInst. This can be revised quite easily once VPInstructions acquire any other form of modeling compares.

The TC==1 part and preliminary CHECK completion of tests are to be uploaded first.
