  [Attributor] Visit droppable uses in AAIsDead

If we ignore droppable users everything only used in llvm.assume (among
other things) is going to be deleted as dead. This is not helpful.
Instead we want to only delete things we actually don't need anymore. A
follow up will deal with loads in a smarter way.
