libstdc++: Rework std::copy/copy_backward/move/move_backward/fill/fill_n algos
Enhance those algos overloads to generalize existing optimization for
__gnu_debug::_Safe_iterator w/o _GLIBCXX_DEBUG mode and for std::deque
iterators.
Also extend __copy_move_a2 ostreambuf_iterator overloads to std::vector and
std::deque iterators.
