carbon.h looking good! Only 1 warning left...no parse errors!
This fixes 3 bugs...
- A couple tricky bugs with type canonicalization. Nested typedef's weren't being
handled properly. For example, the following didn't work:
typdef int __darwin_pid_t;
typedef __darwin_pid_t pid_t;
int getpgid(pid_t);
int getpgid(int);
- The storage class wasn't being preserved. As a result, Sema was complaining
about the following:
extern char *foo;
char *foo;
- various built-ins weren't registered...resulting in spurious warnings.

This is a "small" checkin. #include_next wasn't working properly on
Leopard. This is because the driver has some hard coded paths that
don't work on Leopard. The real fix is to derive them, however I don't
think we need to solve this now. At this point, anyone working on clang
should be able to use Leopard. This fix removed 11 errors processing
"carbon.h". The bug that bubbles up to the top is in MergeFunctionDecl().
As part of digging into this part of Sema, I rearranged some methods
(and changed the visibility).

it to Sema/ASTStreamer (separating the lifetime of ASTContext from
the lifetime of Sema). One day it might be useful to consider creating
a context object implicitly if one isn't provided (using default arguments in
Sema's constructor). At this point, adding this convenience isn't necessary.

the prerocessor will be available via ASTContext).
- Removed the public data member "PP" in ASTContext.
- Changed ASTContext's contructor to take TargetInfo/IdentifierTable explicitly.
- Implicitly create an ASTContext in Sema's constructor. This simplifies
the clients job (and makes ASTContext more private).
--As a side effect, added a "PrintStats" hook to Sema.
To support this level of encapsulation, ASTContext is always dynamically
allocated (by Sema). Previously, ASTContext was being allocated on the
stack. I don't believe this should be a performance issue (since ASTContext
is fairly course grain and tied to the lifetime of Sema currently).

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.

maintain state, and reduces the size of the Preprocessor.h interface.
