This revision is now accepted and ready to land.

Since extending MemDepResult looks not feasable (and replacing it to tag-pointer pair also looks bad because it frequently passed by value), I think we can treat select dependency as Def. It also fits naturally into existing GVN infra, and the meaning of Def dependency is already overloaded (it can be other load/store/alloca/memory intrinsic/etc.)
