Yeah, I'm not quite sure how to handle those. We can't just completely erase
the difference there because they matter for creation of clang asts. One idea
(that just occurred to me) would be to have a sort of a getCanonicalTag() which
maps structure_type to class_type (or the other way around), and then do these
comparisons on the "canonical" tags.
