This fixes two P-high regressions, so I'm bumping its priority for rollup scheduling.

I think this should also fix #137873 (via llvm/llvm-project#129546)

@Kobzol Probably shouldn't show the cases where only the ignore message differs? (Or maybe normalize the version).

[run-make] tests/run-make/compressed-debuginfo-zstd (stage 2): pass -> ignore (ignored if LLVM wasn't build with zstd for ELF section compression (we want LLVM/LLD to be built with zstd support)) (J2)

This might be an issue with download-ci-llvm, where we get a different config (with/without zstd) depending on whether we download or build llvm.

Probably shouldn't show the cases where only the ignore message differs? (Or maybe normalize the version).

I think that seeing the difference in the ignore message is fine, it could be important sometimes (e.g. a test is now ignored for a completely different reason than before).

This might be an issue with download-ci-llvm, where we get a different config (with/without zstd) depending on whether we download or build llvm.

This sounds more worrying, tbh, we should ideally have exactly the same config when building or downloading LLVM 😅
