Not for this CL, but can this go away? I'm guessing that this was added to
support name mangling, which we don't need to do anymore.

Sure.
This CL is only about consolidating everything around Element.
Element itself will be cleaned up and probably enhanced to support for example
(as you requested) CompilationUnit.
