    c++: Require C++11 for g++.dg/opt/pr110879.C [PR110879]
    
    The _M_realloc_insert member does not have the trivial relocation
    optimization for C++98, which seems to be why the _M_end_of_storage
    member does not get optimized away. Make this test unsupported for
    C++98.

            PR libstdc++/110879
            * g++.dg/opt/pr110879.C: Require C++11 or later.
