Initial implementation of anonymous unions (and, as a GNU extension,

structures and classes) in C++. Covers name lookup and the synthesis
and member access for the unnamed objects/fields associated with
anonymous unions.

Some C++ semantic checks are still missing (anonymous unions can't
have function members, static data members, etc.), and there is no
support for anonymous structs or unions in C.
