ee8760b21b Rename macroformalargs -> MacroArgs, as it represents the actual arguments, 
not the formal arguments, to a macro.

678c880a69 Move Preprocessor::isNextPPTokenLParen to Lexer::isNextPPTokenLParen, where 
it more rightly belongs.

3ebcf4e2cd Change Preprocessor::SkippingContents into Lexer::LexingRawMode. Raw mode 
is an intra-lexer property, not a inter-lexer property, so it makes sense
for it to be define here.  It also makes no sense for macros, and allows us
to define it more carefully in the header.

While I'm at it, improve comments and structuring in Lexer.h

completely reversible.  This implements tests 3/4 of

afe603fa7d Implement scanning-for-( more correctly. This implements 
test/Preprocessor/macro_fn_lparen_scan.c, but is not yet complete.

Add some FIXME's about missing diagnostics on empty macro args.  Improve some
comments.

a8654ca2cf Eliminate MultipleIncludeOpt::ReadDirective and all calls to it. Any directives 
that are lexed are made up of tokens, so the calls are just ugly and redundant.

Hook up the MIOpt for the #if case.  PPCExpressions doesn't currently implement
the hook though, so we still don't handle #if !defined(X) with the MIOpt.
