  [Attributor][FIX] Use liveness information of the right function

When we use liveness for edges during the `genericValueTraversal` we
need to make sure to use the AAIsDead of the correct function. This
patch adds the proper logic and some simple caching scheme. We also
add an assertion to the `isEdgeDead` call to make sure future misuse
is detected earlier.

  -----------
  [Attributor][FIX] Heap2Stack needs to use the alloca AS

When we move an allocation from the heap to the stack we need to
allocate it in the alloca AS and then cast the result. This also
prevents us from inserting the alloca after the allocation call but
rather right before.
