This series improv the removal of dead stores:
* kill deadstores in parent-child bascx blocks
* kill redundant in the same basic block

Luc Van Oostenryck (5):
  add testcases for stores simplifications
  extract try_to_kill_store() from kill_dominated_stores()
  volatile stores are never dead
  kill parent's dead stores too
  kill redundant stores (local)
