        - optimize op_jtrue, op_loop_if_true and op_not in various ways
        https://bugs.webkit.org/show_bug.cgi?id=21404
        
        1) Make JSValue::toBoolean nonvirtual and completely inline by
        making use of the StructureID type field.
        
        2) Make JSValue::toBoolean not take an ExecState; doesn't need it.
        
        3) Make op_not, op_loop_if_true and op_jtrue not read the
        ExecState (toBoolean doesn't need it any more) and not check
        exceptions (toBoolean can't throw).
