Aiden Grossman a22d1c2225 Revert "[Polly] Introduce PhaseManager and remove LPM support (#125442)"
This reverts commit e987ab11a6f3d3965ef26fc42c82db3e8b1d56f5.

This broke premerge:
1. https://lab.llvm.org/staging/#/builders/192/builds/9521
2. https://github.com/llvm/llvm-project/actions/runs/19054182009

Notably this did not break inside the PR. Not exactly sure why. I realize that
there is a lot of test churn here, but they're largely in polly where commit
frequency is much lower, so a reapply of the patch should be clean.
