reflect: delete TODO pass safe to packEface don't need to copy if safe==true
valueInterface not copy result in the follow incorrect behavior
w1. x := ValueOf(&v).Elem()
r1. iface := Value.Interface()
w2. x.Set() or x.SetT()
The write operation of W2 will be observed by the read operation of r1,
but the existing behavior is not.
The valueInterface in deepValueEqual can, in theory, pass safe==true to not copy the object,
but there is no benchmark to indicate that the memory allocation has changed,
maybe we don't actually need safe==true here.
