- Cache the typedef, not the type (avoids importing AST/Type.h).
- Emit an error if "id" cannot be found.
- Comment the routine and add a FIXME to reconsider how we emulate GCC's new fangled behavior. This isn't a priority for now, since almost no code depends on having "id" built-in.
- Add a test.

- Make sure default return/argument types (for methods) default to "id".
- Cache the "id" type in Sema...initialize ObjcIdType and TUScope (oops).
- Fix ActOnInstanceMessage to allow for "id" type receivers...still work to do (next).

Fix a latent bug in MinimalActions (created by a recent name change).

Remove Scope argument from ObjC actions that either don't need it or can now use TUScope.
Also improve a recently added comment.

predefined macros.  Previously, these were handled by the driver,
now they are handled by the preprocessor.

Some fallout of this:

1. Instead of preprocessing two buffers (the predefines, then the 
   main source file)  we now start preprocessing the main source 
   file and inject the predefines as a "psuedo #include" from the
   main source file.
2. #1 allows us to nuke the Lexer::IsMainFile flag and simplify
   Preprocessor::isInPrimaryFile.
3. The driver doesn't have to know about standard #defines, the
   preprocessor knows, which is nice for people wanting to define
   their own drivers.
4. This allows us to put normal tokens in the predefine buffer,
   for example a definition for __builtin_va_list that is 
   target-specific, and a typedef for id in objc.

Make sure methods with no return type default to "id".

This fixes a crasher in Sema::MatchTwoMethodDeclarations(), identified by selector-overload.m (just added).

Added Action::ActOnTranslationUnitScope() and renamed Action::PopScope to ActOnPopScope.

Added a Translation Unit Scope instance variable to Sema (will be very useful to ObjC-related actions, since ObjC declarations are always file-scoped).

is inspired by the OCaml implementation of Map, which also uses a functional
AVL tree.

Documentation is currently limited and cleanups are planned, but this code
compiles and has been tested.
