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.
