Issue Description:

Try to compile the following code:

class C {
  init() throws {}
}

class D: C {
  let i: Int
  init(i: Int) {
    self.i = i
  }
}

The compiler views error like
<unknown>:0: error: call can throw, but it is not marked with 'try' and the error is not handled.

D seems to call super.init implicitly, but the error message doesn't imply it.
