And here is the patch for this part.

I have implemented it in such a way that it will also remove several 
layers of move_iterator.

2015-05-04  François Dumont  <fdumont@gcc.gnu.org>

     * include/bits/cpp_type_traits.h
     (std::move_iterator): Delete declaration.
     (std::__is_move_iterator<move_iterator>): Move partial 
specialization...
     * include/bits/stl_iterator.h: ... here.
     (std::__miter_base): Overloads for std::reverse_iterator and
     std::move_iterator.
     * include/bits/stl_algobase.h (std::__miter_base): Provide default
     implementation.

Tested under Linux x86_64.

Ok to commit ?

François
