- Don't crash if a class_method instruction could not be devirtualized. - Improve devirtualization of methods with generic parameters and using dependent types. - Fix a bug in isBindableToSuperclassOf, uncovered while fixing the original bug reported in SR-1206. This bug could lead in certain cases to invocations of a wrong method from the base class, instead of using a method from a derived class. rdar://25891588 and SR-1206
