- fix crash seen when running JavaScriptCore tests

        * kjs/array_instance.cpp: (KJS::ArrayInstance::mark):
        Copy and paste error: I accidentally had code here that was
        making a copy of the HashMap -- that's illegal inside a mark
        function and was unnecessary. The other callsite was modifying
        the map as it iterated it, but this function is not.
