Current standard that LLVM use is c++17. But we generally should support compilers at [least 3 years of compilers](https://llvm.org/docs/DeveloperPolicy.html#updating-toolchain-requirements).

I don't have much knowledge on cherry-picking to release, but the latest release of 20.x could be on Jul 8th (if it even happens, see https://llvm.org/). I have a slight feeling that it may not worth cherry-picking, If LLVM is compiled from source, would it be feasible to just use 21st LLVM branch that will be released soon, [gjasny](https://github.com/gjasny)?
