Subject: Fixed overloading in package objects.

Implementing a warning for the behavior described in SI-1987 gave me
enough of a foot in the door to fix it rather than warning about it. I
suppose this is a variation of rubber ducky debugging.

% scalac -Ylog:typer test/files/run/t1987.scala
[log typer] !!! Overloaded package object member resolved incorrectly.
  Discarded: def duh(n: Double): Unit
  Using: val duh: (n: Double)Unit <and> (n: Long)Unit
