1. it wasn't applying to definitions, only declarations, e.g. int x __asm("foo")
2. multiple definitions were conflicting, they weren't getting merged.
3. the code was duplicated in several places.

qualified name, e.g., 

  foo::x

so that we retain the nested-name-specifier as written in the source
code and can reproduce that qualified name when printing the types
back (e.g., in diagnostics). This is PR3493, which won't be complete
until finished the other tasks mentioned near the end of this commit.

The parser's representation of nested-name-specifiers, CXXScopeSpec,
is now a bit fatter, because it needs to contain the scopes that
precede each '::' and keep track of whether the global scoping
operator '::' was at the beginning. For example, we need to keep track
of the leading '::', 'foo', and 'bar' in
 
  ::foo::bar::x

The Action's CXXScopeTy * is no longer a DeclContext *. It's now the
opaque version of the new NestedNameSpecifier, which contains a single
component of a nested-name-specifier (either a DeclContext * or a Type
*, bitmangled). 

The new sugar type QualifiedNameType composes a sequence of
NestedNameSpecifiers with a representation of the type we're actually
referring to. At present, we only build QualifiedNameType nodes within
Sema::getTypeName. This will be extended to other type-constructing
actions (e.g., ActOnClassTemplateId).

Also on the way: QualifiedDeclRefExprs will also store a sequence of
NestedNameSpecifiers, so that we can print out the property
nested-name-specifier. I expect to also use this for handling
dependent names like Fibonacci<I - 1>::value.

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.
