There should be no difference for the modification.
In LoopUtils.cpp:1337 <https://github.com/llvm/llvm-project/blob/2bb4ebb19e8893634fd2491d55c127b8ba58e637/llvm/lib/Transforms/Utils/LoopUtils.cpp#L1337>, the structure `RewritePhi` is initialized. `PN->getIncomingValue(Phi.Ith)` should be equal to `Phi.ExpansionPoint`.
