Issue Description:

class Food {
    var name: String

    init(name: String) {
        self.name = name
    }

    // This convenience initializer never calls designated initializer.
    // But this code is compilable. 
    convenience init() {
        self.init() 
    }
}

let food = Food()

Convenience initializers are allowed to chain to other convenience initializers, and I don't think we can solve the problem in general. But we could certainly prohibit a convenience initializer that only chains to itself.
