        [Symbian] Fix lastIndexOf() for Symbian

        https://bugs.webkit.org/show_bug.cgi?id=31773

        Symbian soft floating point library has problems with operators

        comparing NaN to numbers. Without a workaround lastIndexOf() 

        function does not work.

        * runtime/StringPrototype.cpp:

        (JSC::stringProtoFuncLastIndexOf):Add an extra test 

        to check for NaN for Symbian.
