c35fbb54 - [VPlan] Use VPReductionPHIRecipe::isOrdered instead of CM (NFC).

[VPlan] Use VPReductionPHIRecipe::isOrdered instead of CM (NFC). Directly retrieve isOrdered from the reduction phi recipe instead of going through the legacy cost model. Split off as suggested in https://github.com/llvm/llvm-project/pull/142322.
