Subject: [PATCH] Always include add_reference in iterator_adaptor.

It's only included for certain configurations but is always used. This
didn't matter in the past because it was transitively included by
is_convertible. But it isn't now on Visual C++ because its itsintrinsic
version is being used, which doesn't require add_reference.
