    libstdc++: Remove dg-error that no longer happens
    
    There was a c++11_only dg-error in this testcase, for a "body of
    constexpr function is not a return statement" diagnostic that was bogus,
    but happened because the return statement was ill-formed. A change to
    G++ earlier this month means that diagnostic is no longer emitted, so
    remove the dg-error.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/20_util/tuple/comparison_operators/overloaded2.cc:
            Remove dg-error for C++11_only error.
