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.
