-Changed the name of TypeRef to QualType. Many diffs.
-Changed the QualType constructor to require Quals be passed. This makes the code a bit
more verbose, however will make the code easier to work on. Given the complexity
of types, this should help spot bogosities.
-Changed the Expr constructor to require a QualType. Same motivation.

Down to 0 warning/errors for Carbon.h. Also made a couple trivial name

of source code.  For example:

$ clang INPUTS/carbon_h.c -arch i386 -arch ppc
prints:
...
/usr/lib/gcc/i686-apple-darwin8/4.0.1/include/mmintrin.h:51:3: note: use of a target-specific builtin function, source is not 'portable'
  __builtin_ia32_emms ();
  ^

because carbon.h pulls in xmmintrin.h, and __builtin_ia32_emms isn't a builtin on ppc.

Though clang now supports target-specific builtins, the full table isn't implemented yet.

whose decl objects are lazily created the first time they are referenced.
Builtin functions are described by the clang/AST/Builtins.def file, which
makes it easy to add new ones.

This is missing two important pieces:
1. Support for the rest of the gcc builtins.
2. Support for target-specific builtins (e.g. __builtin_ia32_emms).

Just adding this builtins reduces the number of implicit function definitions
by 6, reducing the # diagnostics from 550 to 544 when parsing carbon.h.

I need to add all the i386-specific ones to eliminate several hundred more.
ugh.
