Like several other loop passes (the vectorizer, etc) this pass doesn't really fit the model of a loop pass. The critical distinction is that it isn't intended to be pipelined together with other loop passes. I plan to add some documentation to the loop pass manager to make this more clear on that side. LoopSink is also different because it doesn't really need a lot of the infrastructure of our loop passes. For example, if there aren't loop invariant instructions causing a preheader to exist, there is no need to form a preheader. It also doesn't need LCSSA because this pass is only involved in sinking invariant instructions from a preheader into the loop, not reasoning about live-outs. This allows some nice simplifications to the pass in the new PM where we can directly walk the loops once without restructuring them.
