Log:
        PR c++/89660 - bogus error with -Wredundant-move.
        * typeck.c (maybe_warn_pessimizing_move): Only accept (T &) &arg
        as the std::move's argument.  Don't call convert_for_initialization
        when warn_redundant_move isn't on.

        * g++.dg/cpp0x/Wredundant-move8.C: New test.
        * g++.dg/cpp0x/Wredundant-move9.C: New test.
