    Capturing the idea here from a discussion on Discord:
* It is annoying to have to specify tool paths to UTC scripts, but this is something llvm-lit has first-class knowledge of, so no more awkward `--llc-binary`/`--clang`
* llvm-lit knows how to do test discovery, parallel job dispatch, and gives a nice progress bar when you use `-sv`
