[PATCH] D31261: [IR] De-virtualize ~Value to save a vptr

PTAL, I think this is the final form of this patch. I couldn't come up with a cleaner way to allow MemorySSA to retain it's virtual methods. Trust me, I tried.

Then again, extending the Value/User hierarchy isn't really a supported use case. If we want to let people reuse the use/def list machinery with less work, we can tackle that separately from this change.
