They theoretically come from unpacking `repro.tar`. I just saw all the `reproduce.s` tests had shell requirements and assume they came from (at least cargo culting) https://github.com/llvm/llvm-project/commit/cbe62f2f2f1e7e514fdf10d9bfc604921e7eba89. I didn't want to try and remove too many to avoid buildbot churn. Happy to review a PR reenabling this on Windows though if you think that works and it passes premerge.
