; 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.
