[PATCH] D143465: [LoopVectorize] Vectorize the reduction pattern of integer min/max with index. (WIP)

[Mel Chen via Phabricator via llvm-commits]

Mel-Chen updated this revision to Diff 497320.
Mel-Chen added a comment.

Changes:

- Remove function `createInductionSelectCmpTargetReduction`
- Add function `createSentinelValueHandling`
- Fix the start value of SelectCmp and MinMaxIdx

And then I don't know why all FIXME has been fixed, will confirm.
