d478502a - [VPlan] Ensure that IV resume phi for epilogue is always first. (NFCI)

[VPlan] Ensure that IV resume phi for epilogue is always first. (NFCI) Update handling of canonical IV resume phi for the epilogue loop to make sure the resume phi for the canonical IV is always the first phi in the scalar preheader. This makes it easier to retrieve it in preparePlanForEpilogueVectorLoop. For now, we keep an assert to make sure we use the same resume phi as before. This will be removed in the future.
