In Ada, if a class implements an interface and has a dynamic superclass, then the "offset to top" -- the offset that says how to turn a pointer to the interface into a pointer to the whole object -- is stored in the object itself. This patch changes GDB to understand this. Because this only touches Ada code, and because Joel already reviewed it internally, I am checking it in.
