Subject: [v3] reorder headers in <memory>

As suggested a few weeks ago on the libstdc++ list, this patch tweaks
the include order in <memory>, allowing internal library headers to
use shared_ptr and unique_ptr without depending on
<backward/auto_ptr.h>.

        * include/std/memory: Include auto_ptr.h later.
        * include/bits/shared_ptr.h (shared_ptr(auto_ptr<_Up>&&): Remove
        definition.
        * include/bits/shared_ptr_base.h (__shared_ptr(auto_ptr<_Up>&&):
        Likewise.
        * include/bits/unique_ptr.h (unique_ptr(auto_ptr<_Up>&&): Likewise.
        * include/backward/auto_ptr.h (unique_ptr(auto_ptr<_Up>&&): Define.
        (shared_ptr(auto_ptr<_Up>&&, __shared_ptr(auto_ptr<_Up>&&): Likewise.
        * include/std/future: Reduce header dependencies.
        * testsuite/20_util/default_delete/48631_neg.cc: Adjust dg-error line
        numbers.
        * testsuite/20_util/shared_ptr/cons/43820_neg.cc: Likewise.
        * testsuite/20_util/unique_ptr/assign/48635_neg.cc: Likewise.

Tested x86_64-linux, committed to trunk.
