  Log Message:
  -----------
  [LoopUnrollAndJam] Forget scalar evolution dispositions. Do no explicitly forget subloop.

Fixes https://github.com/llvm/llvm-project/issues/58454

Scalar evolution dispositions need to be forgotten to pass verification.

We do not need to forget the subloop since it is automatically forgotten
when forgetting the parent loop.
