multiple stores with a single load. We create the wide loads and stores (and their chains) before we remove the scalar loads and stores and fix the DAG chain. We attempted to merge loads with a different chain. When that happened, the assumption that it is safe to RAUW broke and a cycle was introduced. llvm-svn: 165148
