Alan Donovan 43c97eab79 go.tools/go/pointer: fix solver nontermination bug due to reflective type construction cycles. 
Programs such as this cause the PtrTo solver to attempt to
enumerate an infinite set of types {T, *T, ..., *******T, etc}.

        t := reflect.TypeOf(T{})
        for {
                t = reflect.PtrTo(t)
        }

The fix is to bound the depth of reflectively created types at
about 4 map/chan/slice/pointer constructors.

+ test.
