...<https://github.com/llvm/llvm-project/commit/ 777180a32b61070a10dd330b4f038bf24e916af1>. This is just a quick fix to get copmilerplugins buiding again with latest LLVM/Clang trunk. Ideally, we should get rid of as many of those (potentially expensive) conversions from llvm::StringRef to std::string as possible.
