This is a reland of 6c6132880a
Original change's description:
> [Liftoff] Implement parallel register moves
>
> This was not implemented so far, leading to lots of clusterfuzz issues.
> Testing this feature would require complicating the interface a lot and
> exposing more implementation details in the header file, hence we just
> go with regression tests for now.
