They were both caused by the infinite recursion in the operator== for
tracker_allocator, which should be fixed.

However, my change to std::deque's move constructor introduced some
new failures, mostly due to dg-error line numbers that need to change,
but one real failure in 23_containers/deque/allocator/move_assign.cc

I'm not sure whether the right approach is to violate the requirement
that deque's move constructor move constructs the allocator, (which I
changed to copy construction, to meet the exception safety guarantee
that the RHS of the move construction maintains its invariants) or to
change the invariant so that a deque doesn't always have a map
allocated.

I'll fix it asap.
