>> getting this all right and enabled by default with the first commit is probably not achievable

Maybe yes, well…

If we could pick some the most obvious and profitable cases and enable this pass for them (simple heuristics, otherwise be conservative), plus, if we have PGO data, specialize very hot functions?

Yeah, I see concerns that another off by default pass is not ideal. Just look how many passes are in tree and disabled.

So +1 if we can run this pass even with conservative heuristics.
