Issue Description:

When a function with the same name (not necessarily signature) is called inside other function an error is produced. A very reduced example below produces the following error; Argument passed to call that takes no arguments.

extension String {
    func round() -> CGFloat {
        let a: CGFloat = round(CGFloat(1.0))
        return a
    }
}

The correct behavior would be to call the correct function - round(x: CGFloat in this example.

Comment by Maximilian Hünenberger (JIRA)

As of Xcode 8 beta 5 this is still not solved and it occurs with any call to a global function which has the same name (without considering argument labels):

func test(i: Int) {}
class Test {
    func test() {
        test(i: 0)
    }
}
