comments ;) How this is different from BOTTOM in the lattice?
The patch overall seems to make sense. Please add describing comment on the
top of ipa-cp as we are now diverging from classical ipa-cp formulation
somewhat (but I can't seem to justify separate devirtualization pass that would
do precisely the same as ipa-cp does but at types only)
I guess patch is Ok with the comment for pretty-ipa, we can deal with the
unnecesary clonning issue later.
