When lowering `select+icmp` we have an optimization that allows us to avoid materializing the icmp result. We were accidentally not masking the high bits for i8 and i16 in this case. Issue #5498 reported this as an illegal instruction but what was happening there was that the invalid select caused a division by zero.
