Updated patch to simplify the helper trait, and to include <memory>
instead of <algorithm> in the unit test for copy_uninitialized:

Use __builtin_memmove for trivially copy assignable types

2018-07-19  Glen Joseph Fernandes  <glenjofe@gmail.com>

    * include/bits/stl_algobase.h
    (__is_simple_copy_move): Defined helper.
    (__copy_move_a): Used helper.
    (__copy_move_backward_a): Likewise.
    * testsuite/20_util/specialized_algorithms/uninitialized_copy/1.cc:
    New test.
    * testsuite/25_algorithms/copy/58982.cc: Updated tests.
    * testsuite/25_algorithms/copy_n/58982.cc: Likewise.
