    libstdc++: Make allocator equality comparable in tests
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/23_containers/unordered_map/cons/default.cc: Add
            equality comparison operators to allocator.
            * testsuite/23_containers/unordered_set/cons/default.cc:
            Likewise.
    
    (cherry picked from commit 2eff2a3cb521c58212885a3dca638764285b5691)
