is duplicated by:

• SR-1375 Availability of default values in initializer or generics in class definition may prevent swift from inheritance of initializer.
• SR-924 Subclass of generic class has no initializers

Issue Description:

For such code:

public class A<T : Any> { 
    public init(n : Int) { 
        print("A")
    } 
} 
public class B : A<Int> {
}
let x = B(n: 123)

The two rules from documation have no effect.

Rule 1 “If your subclass doesn’t define any designated initializers, it automatically inherits all of its superclass designated initializers.”
Rule 2 “If your subclass provides an implementation of all of its superclass designated initializers—either by inheriting them as per rule 1, or by providing a custom implementation as part of its definition—then it automatically inherits all of the superclass convenience initializers.”
