Reject template-ids containing literal-operator-ids that have a dependent
nested-name-specifier, rather than crashing. (In fact, reject all
literal-operator-ids that have a non-namespace nested-name-specifier). The
grammar doesn't allow these in some cases, and in other cases does allow them
but instantiation will always fail.
