[PATCH] D84451: [LV] Tail folded inloop reductions.

[Dave Green via Phabricator via llvm-commits]

dmgreen updated this revision to Diff 293368.
dmgreen added a reviewer: SjoerdMeijer.
dmgreen added a comment.

I have updated this to include a getFirstNonPhi() method on VPBasicBlock, which helps to move some of this logic into a nicer place. This way the Block Mask is still created before any other instructions, but after the phi nodes in the block.
