Path through the class hierarchy taken by casts between base and derived classes (see implementation of CastConsistency() for a full list of cast kinds that have a path).
For each derived-to-base edge in the path, the path contains a CXXBaseSpecifier for the base class of that edge; the entries are ordered from derived class to base class.
For example, given classes Base, Intermediate : public Base and Derived : public Intermediate, the path for a cast from Derived * to Base * contains two entries: One for Intermediate, and one for Base, in that order.
