Driver: Add argument translation utilities to ArgList.
 - Support things like telling which -ffoo -fno-foo option won, and
   forwarding all arguments matching a certain set of options to the

Driver: Add assert and FIXME; arguments which act as linker inputs

Driver: Add "d" flag to Options.def for options which are completely
handled by driver.
 - This is not very precise, we use it to drive the "forward-to-gcc"
   predicate, when trying to talk to a generic gcc tool.

 - Slightly better than what ccc was doing, and should be good
   enough. Platforms which want a robust driver should implement a
   proper tool chain.

The scope representation can now be either a DeclContext pointer or a

information about the actual spelling (e.g., which typedef did the

Fix Type::getDesugaredType() to remove all direct sugar on
a type.  For example, if we have a typedef of a typeof of

Implement instantiation of enums within class templates. This isn't
quite as great as it sounds, because, while we can refer to the
enumerator values outside the template, e.g.,

  adder<long, 3, 4>::value

we can't yet refer to them with dependent names, so no Fibonacci
(yet).

InstantiateClassTemplateSpecialization is getting messy; next commit
will put it into a less-ugly state.

Add ArgList::MakeArgString and make ArgList::Make* const.
 - Slightly strange, but the idea is that the ArgList data structure
   is primarily a list of arguments; we want to allow clients to still

Almost complete implementation of rvalue references. One bug, and a few unclear areas. Maybe Doug can shed some light on some of the fixmes.

Build system changes to use TableGen to generate the various
diagnostics. This builds on the patch that Sebastian committed and
then revert. Major differences are:

  - We don't remove or use the current ".def" files. Instead, for now,
    we just make sure that we're building the ".inc" files.
  - Fixed CMake makefiles to run TableGen and build the ".inc" files
    when needed. Tested with both the Xcode and Makefile generators
    provided by CMake, so it should be solid.
  - Fixed normal makefiles to handle out-of-source builds that involve
    the ".inc" files.

I'll send a separate patch to the list with Sebastian's changes that
eliminate the use of the .def files.

Driver: Implement majority tool binding logic.
 - Still need code for determining proper output location.

 - Doesn't work yet, of course, as the host isn't providing real
   tool chains.

 - Interface still has a few warts, but has gotten a nice bit of
   polish during the rewrite.
