I think the way this may need to work is to find out where we're getting the file name from and seeing how long-lived that string is. It's passed here as a `StringRef`, and it would nice if we can store it as a `StringRef` in the `EmbedAnnotationData` rather than as a `std::string`. My guess is that the name comes from the `FileManager` and is as long-lived as the `SourceManager` which is owned by `ASTContext`, but we'd need to verify that.
