Okay, that makes sense.  I can drive this from a CXXRecordDecl visitor,
something like:

bool VisitCXXRecordDecl( CXXRecordDecl * r )
{
   if ( r->isThisDeclarationADefinition() )
   {
      for ( CXXRecordDecl::field_iterator b = r->field_begin(), e =
r->field_end() ;
            b != e ; ++b )
      {
         const FieldDecl * a = *b ;

         myVisitFieldDecl( a ) ;
      }
   }

   return true ;
}

I found getInstantiatedFromMemberClass() in the docs, and it appears I can
use this to see if the template is an instantiation.  However I'm having
trouble figuring out how to tell if the CXXRecordDecl is a template or not
(since I want to visit the fields of all instantanted template class decls
and all the fields of the plain old non-template classes).

I don't see a isTemplateClass() or anything like that?  How would such a
check be done?
