The earlier reduction "scalarization" was only applied to a chain of *innermost* and *for* loops. This revision generalizes this to any nesting of for- and while-loops. This implies that reductions can be implemented with a lot less load and store operations. The chaining is implemented with a forest of yield statements (but not as bad as when we would also include the while-induction).
