Expand description

Visits free regions in the type that are relevant for liveness computation. These regions are passed to OP.

Specifically, we visit all of the regions of types recursively, except if the type is an alias, we look at the outlives bounds in the param-env and alias’s item bounds. If there is a unique outlives bound, then visit that instead. If there is not a unique but there is a 'static outlives bound, then don’t visit anything. Otherwise, walk through the opaque’s regions structurally.
