    c++: Avoid ICE with dependent attribute on type.

    We previously happened to accept this testcase, but never actually did
    anything useful with the attribute.  The patch for PR86379 stopped using
    TREE_TYPE as USING_DECL_SCOPE, so 'using A::b' no longer had TREE_TYPE set,
    so the language-independent decl_attributes started crashing on it.

    GNU attributes are more flexible in their placement than C++11 attributes,
    so if we encounter a dependent GNU attribute that syntactically appertains
    to a type rather than the declaration as a whole, move it to the
    declaration; that's almost certainly what the user meant, anyway.
