For our custom JIT compiler pipeline we want to have a flexible control on pipeline behavior,
which might have a number of different applications. Immediate one is the ability to gracefully
shut down the compilation that takes too long.
Most likely this particular need is completely off the roster of a static compiler though.

I would like to stress that we consider OptBisect to be more than just "bisector", but rather the only
available way of skipping optimization passes with an arbitrarily complex control pattern.
