This isn't right for two reasons:

1) "#warning foo" should work with PTH.
2) "#warning la'la" should be handled correctly, even though "'la" is  
not a valid token.

I suggest removing the 'CurPTHLexer->DiscardToEndOfLine();' and making  
it an assert(0) FIXME.  We'll need to introduce a new token type for  
this, and have the PTH generation phase handle this specially.
