Here is a new version that also passes the tests. I guess we will have
plenty of time during stage1 to notice if it causes problems. We could
probably move the new definitions of __distance to
bits/stl_iterator_base_funcs.h, I don't have a clear preference.
Seems like a great start and we can improve it later if needed.
OK for trunk, thanks.
We should also look into applying the same optimisation for
__gnu_debug::list, as long as we don't lose the ability to detect
errors like std::distance(l1.begin(), l2.end()) where &l1 != &l2.
