The idea being that a bailout need to recover the side-effects which are supposed to be executed in baseline at the point where we are resuming. If one side-effect was not ran, it need to be recovered. Thus we should list all the latest alias sets as part of the resume points.

The goal of this issue, is to save the store operations on resume points such that we can "Sink" them down in the graph as long as they do not collide with any other aliased instructions.

For example, this would be useful to do LICM by moving Store operations at the bottom of loops.
