This adjusts the return type to match the resolution of LWG 3672. There
is no functional difference, because decltype(auto) always deduced a
value anyway, but this makes it simpler and consistent with the working
draft.

* include/bits/stl_iterator.h (common_iterator::operator->):
Change return type to just auto.
