If genOpenMPReduction is called her it replaces the normal operations (e.g. `arith.addi`) with an `omp.reduction` operation that is no longer used/needed with the new reduction lowering. At some point when all operations have moved to the new reduction style, those operations should be removed entirely from the OpenMP dialect.
