Use a modeling similar to SCF ParallelOp to support arbitrary parallel reductions. The two main differences are: (1) reductions are named and declared beforehand similarly to functions using a special op that provides the neutral element, the reduction code and optionally the atomic reduction code; (2) reductions go through memory instead because this is closer to the OpenMP semantics.
