Are there any other known passes that present the same level of complexity wrt OptBisect interaction?

Andy already mentioned SelectionDAGISel. I'll bet there are some target-specific passes that have similar needs, though I can't think of any offhand.

Depending on how the OpenMP architecture discussions go, there could certainly be OMP lowering passes that must be run and may or may not do optimization, where "run at OptLevel::None" support would be useful. So that's some number of IR-level (non-codegen) passes that have more complexity than the typical IR-level pass.
