We need to make sure the data part returned by sampler messages is
always aligned to a physical register. Just like the residency data
lives in a single physical register after the data.
Lowering a vec3 16bits per components led to a half a physical
register allocation which then confused the descriptor lowering
(expecting physical register units).
