Bug ID: 20185

Source code demonstrating problem
Build the attached code.
I don't expect -[ColoredBox initWithSideLength:] to generate a warning/error
since the method can never return (the call has been rejected and should be
fixed at development-time.)
We use this idiom quite a but when a subclass shouldn't be initialized directly
with the superclass's designated initializer.
It would be great if clang allowed us to use the objc_designated_initializer
attribute without the extraneous warning.
