<div class="">I for one have always found this to be *incredibly*
annoying. It just adds a massive amount of noise to the
debugging experience when viewing -print-after-all and searching
for where some specific transform happened</div>

This I can definitely understand, but to this end, maybe we should
have a setup where -print-after-all just doesn't reprint IR if the
previous pass didn't change anything?<br>
