80cc28b6 - [VPlan] Normalize selects in optimizeFindIVReductions. (#191517)

[VPlan] Normalize selects in optimizeFindIVReductions. (#191517) Follow-up to https://github.com/llvm/llvm-project/pull/191166. Unify code to create new selects in optmizeFindIVReductions to simplify the code paths and make it easier to include the header mask correctly if needed. If no new select needs to be created, just use the original backedge value.
