Thanks for doing that. I just updated the patch to install `llvm-testing-tools` instead. I think we'll need this on all the platforms that we test on, which might be annoying to setup (Windows, macOS, Linux). That's also why a pure-Python package is simpler.

Do you think it would be feasible to provide this package on Windows and macOS as well?
