dump-func-sig is a tool I hacked together which uses clang tooling to parse the files as much as it can and then prints out reconstructed function signature and it's location.

Ten do diff of clang-N and nvcc-N/decls with a lot of regex filtering for argument names, etc. No diff tool does good enough job, so I've missed few functions.
