        Description

        In PhaseIdealLoop::create_outer_strip_mined_loop():

                    while (be->is_Store() && old_new[be->_idx] != NULL) {
                      ShouldNotReachHere();
                      be = be->in(MemNode::Memory);
                    }

        and
                  while (be->is_Store() && old_new[be->_idx] != NULL) {
                    ShouldNotReachHere();
                    be = be->in(MemNode::Memory);
                  }

        This code would trigger with sunk stores and stores on backedge. I couldn't trigger it with a test case and it wasn't caught by testing. Still, if this happens in the wild it would cause a crash.
