       * include/bits/stl_algobase.h
       (__is_simple_copy_move): Defined helper.
       (__copy_move_a): Used helper.
       (__copy_move_backward_a): Likewise.
       * testsuite/25_algorithms/copy/58982.cc: Updated tests.
       * testsuite/25_algorithms/copy_n/58982.cc: Likewise.

Tested x86_64-pc-linux-gnu.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68350 looks related but for adifferent function. Hopefully the issues discussed there don't applyhere...
