I've added DeclBase.cpp here (Chris was fine with this change at the 
previous related patch):
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20080602/006009.html

In the currently attached patch there are only the AST-related changes 
(introducing the C++ decl subclasses); these are the important ones.

Making 'this' const is so that the error diagnostics can report its type 
as "[class name]* const". This convention is followed by both gcc and msvc.
