• 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).
