When a derived class does not inherit a designated initializer from its base class, we override the designated initializer's vtable entry with a stub which traps with a fatal error. The stub cannot be called and clients do not need to be aware of its existence, so don't print it at all in the module interface. Fixes rdar://problem/71122015 / https://bugs.swift.org/browse/SR-13832.
