* store-motion.c (struct st_expr): Make pattern_regs a vector.
(extract_mentioned_regs): Append to a vector instead of
returning a rtx_expr_list.
(st_expr_entry): Adjust.
(store_ops_ok): Likewise.
(store_killed_in_insn): Likewise.
(find_moveable_store): Likewise.
This is fine. Though one has to wonder if a different representation
than lists/vecs would work better given the walks. A bitmap for example
might work well since I think we just need to track register #s.
