cleaner visitor framework.

Added a visitor for declarations, which is quite similar to the
visitor for statatements.

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.

stubs for those types we don't yet know how to instantiate (everything
that isn't a template parameter!).

We now instantiate default arguments for template type parameters when
needed. This will be our testbed while I fill out the remaining
type-instantiation logic.

This change refactors and cleans up our handling of name lookup with
LookupDecl. There are several aspects to this refactoring:

  - The criteria for name lookup is now encapsulated into the class
  LookupCriteria, which replaces the hideous set of boolean values
  that LookupDecl currently has.

  - The results of name lookup are returned in a new class
  LookupResult, which can lazily build OverloadedFunctionDecls for
  overloaded function sets (and, eventually, eliminate the need to
  allocate member for OverloadedFunctionDecls) and contains a
  placeholder for handling ambiguous name lookup (for C++).

  - The primary entry points for name lookup are now LookupName (for
    unqualified name lookup) and LookupQualifiedName (for qualified
    name lookup). There is also a convenience function
    LookupParsedName that handles qualified/unqualified name lookup
    when given a scope specifier. Together, these routines are meant
    to gradually replace the kludgy LookupDecl, but this won't happen
    until after we have base class lookup (which forces us to cope
    with ambiguities).

  - Documented the heck out of name lookup. Experimenting a little
    with using Doxygen's member groups to make some sense of the Sema
    class. Feedback welcome!

  - Fixes some lingering issues with name lookup for
  nested-name-specifiers, which now goes through
  LookupName/LookupQualifiedName.

parameters, with some semantic analysis:
  - Template parameters are introduced into template parameter scope
  - Complain about template parameter shadowing (except in Microsoft mode)

Note that we leak template parameter declarations like crazy, a
problem we'll remedy once we actually create proper declarations for
templates. 

Next up: dependent types and value-dependent/type-dependent
expressions.
