Chris Lattner a81b336ba8 Switch TargetInfo::getTargetDefines from using an std::map<std::string, ...> to using
a llvm::StringMap.  This dramatically reduces the startup time of the preprocessor,
speeding up -Eonly on xalankbmk by 2.2%.

Chris Lattner 4481b428db A significant refactoring of the type size stuff to also
compute type alignment.  This info is needed for struct layout.

Chris Lattner 23b7eb677d Finally bite the bullet and make the major change: split the clang namespace
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.

Chris Lattner 10a5b387cc Add support for target-specific builtins, including detecting nonportability
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.
