CWG 1691 changed the definition of the namespaces associated with a class
type or enumeration type.
For a class type, the associated namespaces are the innermost enclosing
namespaces of the associated classes. For an enumeration type, the associated
namespace is the innermost enclosing namespace of its declaration.
This also fixes CWG 1690 and CWG 1692.

The goal here is to exercise each rule in [basic.lookup.argdep] at least once.
These new tests expose what I believe are 2 issues:
1. CWG 1691 needs to be implemented (p2: [...] Its associated namespaces are
the innermost enclosing namespaces of its associated classes [...]) The
corresponding tests are adl_class_type::X2 and adl_class_type::X5.
2. The end of paragraph 2 ([...] Additionally, if the aforementioned set of
overloaded functions is named with a template-id, its associated classes
and namespaces also include those of its type template-arguments and its
template template-arguments.) is not implemented. Closely related, the
restriction on non-dependent parameter types in this same paragraph needs
to be removed. The corresponding tests are in adl_overload_set (both issues
are from CWG 997).
