What's your concern exactly? The behavior is well-defined, at least as
long as we don't shift far enough to have integer overflow, and I believe
in most of these cases that's not possible. In int8shl etc, you just get
whatever the machine does with that, which seems fine to me; we do not
document any particular semantics for such cases.
