[committed] libstdc++: Skip failing std::array test for debug mode

[Jonathan Wakely via Gcc-patches]

Tested powerpc64le-linux, pushed to gcc-10.


The __gnu_debug::array type isn't three-way comparable in constant
expressions. The __gnu-debug::array type has been removed in gcc-11
anyway, so just skip the test rather than fixing it.

libstdc++-v3/ChangeLog:

        * testsuite/23_containers/array/comparison_operators/96851.cc:
        Skip test in debug mode.
