b8407b33 - [PrintAsObjC] Handle the importer's compatibility typealiases. (#10042)

[PrintAsObjC] Handle the importer's compatibility typealiases. (#10042) These are TypeAliasDecls whose Clang nodes are not TypedefNameDecls. This worked all right for classes, but dropped the tag keyword (e.g. 'struct') for tag decls with names of their own, and didn't print any name at all for C types that used the typedef-for-anonymous-tag pattern. rdar://problem/32514335
