Thanks for working on this!

I think, in practice, what we should do is some combination of assumes and IPSCCP doing what it can.
I don't think we should throw away IPA info because the more local optimizations may still be able to do something better with it.
(IE i don't think IPSCCP will get everything, and so i feel we should expose what it discovers some way that is not ephemeral)
