Issue Description:

I get a crash if i try to compile the following code

import Foundation
import CoreGraphics

public extension CGPath {
    public convenience init(roundedRect rect: CGRect, corner: CGSize) {
        self.init(roundedRect: rect, cornerWidth: corner.width, cornerHeight: corner.height, transform: nil)
    }
}

Output:
<unknown>:0: error: unable to execute command: Segmentation fault: 11
<unknown>:0: error: compile command failed due to signal (use -v to see invocation)

Version:
Apple Swift version 3.0 (swiftlang-800.0.30 clang-800.0.24)

Comment by Stephan Michels (JIRA)

Now, I don't any longer segmentation fault, but I still can't create an convenience constructor:

error: BadAccessPlayground.playground:13:24: error: convenience initializers are not supported in extensions of CF types
public convenience init(roundedRect rect: CGRect, corner: CGSize) {

This is correct. We have no way to compile such an initializer.

Specifically, convenience initializers can be inherited, and your new one can't be in a safe way. The feature we need here is what we call "factory initializers" inside the compiler. (It's not out of the question, either! Just still needs some design.)
