Note that:
- This loop is interchangeable: the top-to-bottom,
left-to-right execution order is also valid since all
dependence constraints (as shown by the arrows) are still satisfied.
- The inner loop is not vectorisable since there is a dependence
chain linking successive iterations.
- Interchanging the loop does not improve vectorisability.
