<pre>Although not required by the standard (yet), allow value types
to be incomplete types can be very useful when declraing recursive
data structures:
struct A {
std::vector<A> v;
};
Comparing to libstdc++, currently
forward_list<Incomplete>
and
deque<Incomplete>
are not supported by libc++.
Here are the proposed changes:

The later one requires probably an ABI immigration. We don't know what to do
yet.</pre>
