Even at -O0, we fall back to SDAG when we hit intrinsics, and if the intrinsic is a memset/memcpy/etc. we might normally use vector types. At -O0, this is probably not a good idea (because, if there is a bug in the lowering code, there would be no good way to turn it off). At -O0, only use scalar preferred types.
