Thanks for taking a look! Now the LLVM and Clang parts are good to go, but I'd like to ideally merge this once the compiler-rt parts (https://github.com/llvm/llvm-project/pull/76261) is also good to go. 

I guess the LLVM part could land mostly independently, but the Clang part should have complementing compiler-rt support to start with I think
