by decaying __builtin_va_list's type when forming builtins.  On
x86-64 (and other targets) __builtin_va_list is a typedef for
an array.

lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.

theoretically useful, but not useful in practice.  It adds a bunch of 
complexity, and not much value.  It's best to nuke it.  One big advantage
is that it means the target interfaces will soon lose their SLoc arguments
and target queries can never emit diagnostics anymore (yay).  Removing this
also simplifies some of the core preprocessor which should make it slightly
faster.

Ted, I didn't simplify TripleProcessor, which can now have at most one
triple, and can probably just be removed.  Please poke at it when you have
time.

Add more intrinsics. We can now correctly parse both Carbon.h and Cocoa.h without having to do -arch ppc.

Add builtin type signature support for vector types. Add correct type signatures for a bunch of MMX builtins. We now parse all the intrinsics in mmintrin.h

it is used by "tgmath.h" (so we need to support it). It might also come in handy when
developing the overloaded function macros for OpenCU.

Next check-in will make this an integer constant expression...

out of the llvm namespace.  This makes the clang namespace be a sibling of
llvm instead of being a child.

The good thing about this is that it makes many things unambiguous.  The
bad things is that many things in the llvm namespace (notably data structures
like smallvector) now require an llvm:: qualifier.  IMO, libsystem and libsupport
should be split out of llvm into their own namespace in the future, which will fix
this issue.

-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.

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.
