This commit enhances the GIMPLE frontend to support the REF_REVERSE_STORAGE_ORDER flag for memory references. Previously, it was difficult to determine if this flag was set on a MEM_REF. The change allows the GIMPLE frontend to set this flag and also enables it to be dumped in GIMPLE mode, aiding in debugging and ensuring correct handling of memory access order.
