Test the lookup I wasn't sure would be done properly after the last patch.

Clang reasonably adds all the base specifiers in one pass;  this is now required
for correctness to prevent lookup from going mad.  But this has the advantage of
establishing the correct context when looking up base specifiers, which will be
important for access control.
