And looking at `TargetLibraryInfo`, all of the functions are in this header, so I assumed it's intentional to keep this type self-contained in this header, as it's public API, which is why I add `ClVectorLibrary` to Impl to pass it back to `TargetLibraryInfo`. For `TargetLibraryInfoImpl`, it's ok to have the implementation outside of the header. I can give it a try if keeping the class implementation/definition self-contained in the header isn't important.

Ok, I moved it to .cpp, thanks!
