I assume this would be a private bot? It can't be a public bot, since LLVM isn't even on C++17, let alone C++20, and so it shouldn't be part of minimum requirements that somebody has a compiler that can build C++20. Whilst I personally am quite happy with moving LLVM forward, I develop on Windows primarily, so don't have the same need to support a long tail of old *nix versions etc.

@BRevzin, you should a) mention the u8/const char* issue in the description too, and also what compiler you used to build this with. I fully expect at this stage that there are some C++20 compilers that might have slightly different interpretations of things which this won't resolve, so knowing which one this is intended to work with could help with historical research.
