class. The thing with Objective C classes is the debug info might have a definition that isn't just a forward decl, but it is incomplete. So we need to look and see if we can find the complete definition and avoid recursing a lot due to the fact that our accelerator tables will have many versions of the type, but only one complete one. We might not also have the complete type and we need to deal with this correctly. llvm-svn: 145759
