Douglas Gregor 4165bd6772 Implement computation of the final overriders for each virtual ... function within a class hierarchy (C++ [class.virtual]p2). We use the final-overrider computation to determine when a particular class is ill-formed because it has multiple final overriders for a given virtual function (e.g., because two virtual functions override the same virtual function in the same virtual base class). Fixes PR5973. We also use the final-overrider computation to determine which virtual member functions are pure when determining whether a class is abstract or diagnosing the improper use of an abstract class. The prior approach to determining whether there were any pure virtual functions in a class didn't cope with virtual base class subobjects properly, and could not easily be fixed to deal with the oddities of subobject hiding.
