- Rename 'CurToken' and 'LastToken' to 'CurTokenIdx' and 'LastTokenIdx'
  respectively.
- Add helper methods GetToken(), AdvanceToken(), AtLastToken() to abstract away
  details of the token stream. This also allows us to easily replace their
  implementation later.

Rewrote PTHLexer::Lex by digging through the sources of Lexer again.  Now we can do basic macro expansion using the PTHLexer.

(temporary hack) to test the PTHLexer is that whenever we would create a Lexer
object we instead raw lex a memory buffer first and then use the PTHLexer. This
logic exists only to driver the PTHLexer and will be removed/changed in the
future. Note that the regular path using normal Lexer objects is what is used by
default.

of doing the lookup_decl, the hash lookup is cheap.  Also,
typeid doesn't happen enough in real world code to worry about
it.

I'd like to eventually get rid of KnownFunctionIDs from Sema
also, but today is not that day.

since this is only done if the namespace hasn't already been looked up.

being called to be converted to a reference-to-function,
pointer-to-function, or reference-to-pointer-to-function. This is done
through "surrogate" candidate functions that model the conversions
from the object to the function (reference/pointer) and the
conversions in the arguments.

Use PreprocessorLexer::getFileID() instead of Lexer::getFileLoc().  This is an intermediate step to having getCurrentLexer() return a PreprocessorLexer* instead of a Lexer*.

  Functor f;

This is the easy part of handling calls to objects of class type 
(C++ [over.call.object]). The hard part (coping with conversions from
f to function pointer or reference types) will come later. Nobody uses
that stuff anyway, right? :)
