Chris Lattner 0c6c034c48 Two fixes: 
1. Allow argument list of a call to be empty.
2. Handle expressions in a statement context that start with an identifier.
   These are nasty to handle due to the 'label:' production which requires
   having two tokens of look-ahead, or by having tricky code (which we
   choose to do).
