    libstdc++: Fix tests that fail with old std::string ABI
    
    These two tests have started to fail with the old std::string ABI. The
    scan-assembler-not checks fail because they match debug info, not code.
    
    Adding -g0 to the test flags fixes them.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/21_strings/basic_string/modifiers/assign/char/move_assign_optim.cc:
            Do not generate debug info.
            * testsuite/21_strings/basic_string/modifiers/assign/wchar_t/move_assign_optim.cc:
            Likewise.
