template<class ForwardIterator> void uninitialized_value_construct(ForwardIterator first, ForwardIterator last);
Effects: Equivalent to:
for (; first != last; ++first)
  ::new (static_cast<void*>(addressof(*first)))
    typename iterator_traits<ForwardIterator>::value_type();
template<class ForwardIterator, class Size> ForwardIterator uninitialized_value_construct_n(ForwardIterator first, Size n);
Effects: Equivalent to:
for (; n > 0; (void)++first, --n)
  ::new (static_cast<void*>(addressof(*first)))
    typename iterator_traits<ForwardIterator>::value_type();
return first;
