[swift-dev] Function overload resolution

[Nevin Brackett-Rozinsky]

The new diagnostic is fine, the problem is that there should not be an
error at all. If there is only one function with the proper signature, the
compiler should not invent a non-existent ambiguity.

The situation I encountered involves functions of different arities, so it
should be straightforward to select the correct one, yet it still fails to
compile. I'd like to make it work.
