    libstdc++: Remove test dependency on _GLIBCXX_USE_C99_STDINT_TR1
    
    This should have been done in r9-2028-g8ba7f29e3dd064 when
    std::shared_mutex was changed to be defined without depending on
    _GLIBCXX_USE_C99_STDINT_TR1.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/experimental/feat-cxx14.cc: Remove dependency on
            _GLIBCXX_USE_C99_STDINT_TR1.
    
    (cherry picked from commit 2c04284abe5d5f1148c709a769f3b83bee2485d0)
