Jordan Rose e5fc17843e Allow overrides to leave out the ownership qualifier of the decl they override. ...

If they do provide it, however, it must match. So the following combinations
are valid:

  weak var -> override weak var
  weak var -> override var

but these are not:

  var -> override weak var
  weak var -> override unowned var

To be fully correct, we should be cloning the attribute down and adjusting
the type of the overriding property, but I'd rather not touch that right now.
