Thanks for working on this.
PGOEdge is shared by PGO instrumentation pass and PGO profile-use pass. We cast away const for PGO instrumentation. But for PGO profile-use, we don't change the BB. I would prefer to keep the const for profile-use passes. So I think a better fix is to make PGOEdge a template class, one with const and one without.
