Chris Lattner f4c68741d4 fix the second half of PR4006 and rdar://6807000 by treating 
() as being either zero arguments or one empty argument depending
on situation.

Chris Lattner 249c38bb02 Fix PR4006, incorrect handling of __VA_ARGS__ when it was the first token 
in a function-like macro body.  This has the added bonus of moving some
function-like macro specific code out of the object-like macro codepath.

Chris Lattner c17925da61 Substantially restructure function-like macro argument parsing. 
Highlights: PP::isNextPPTokenLParen() no longer eats the ( 
when present.  We now simplify slightly the logic parsing
macro arguments.  We now handle PR3937 and other related cases
correctly.
