We try to avoid useless replacement in order not to create useless
load/store statements and this one happened to be considered useless
too.  Fortunatly the code specifically deletes the load from s.i
because it knows it cannot contain anything meaningful and so I hope
to insert creation of an SSA name that would trigger the warning
there.
