-; When the extractelement is converted to a load the store can be re-used.
-; This will, however, introduce a cycle into the selection DAG (the load
-; of the extractelement index is dependent on the store, and so after the
-; conversion it becomes dependent on the new load, which is dependent on
-; the index).  Make sure we skip the store, and conservatively instead
-; use a store to the stack.
