When we're checking a friend function template in an out-of-line class
definition, we may not have a scope corresponding to the namespace
where that friend function template actually lives. Work around this
issue by faking up a scope with the appropriate DeclContext.
This is a bit of a hack, but it fixes <rdar://problem/10204947>.
