[committed] libstdc++: Remove dg-error that no longer happens

[Jonathan Wakely via Gcc-patches]

Tested x86_64-linux, pushed to trunk.



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.
