If we really treat them as normal passes, they should be moved to a header file. If we treat them as testing tools only, we put them in .cpp file in an anonymous namespace. It looks confusing to be not in header file and in `llvm` namespace.
Or perhaps, we don't touch these no-op passes, and add a comment saying we're overriding the `name()` computing here to make tests cleaner?
