This needs to specify atomicity as well. This is much more important to for 16 byte operations than smaller accesses, as this might require stop-the-world semantics depending on the host.
According to section 1.4 Storage Atomicity, we need no more than 8-byte atomicity for these vector operations, and then the following the alignment bits down.
So: MO_128 | MO_ATOM_IFALIGN_PAIR, r~
