Definite initialization for initializers relying on a separate ivar initializer.

When we decide to emit a separate ivar initializer method (via the
Objective-C entry point -.cxx_construct), we no longer initialize the
ivars within the initializer. This only happens for derived classes,
so teach DI about uninitialized 'self' values that require a
super.init call but don't require the ivars to be initialized.
