(or (bool?A:B),(bool?C:D)) --> (bool?(or A,C):(or B,D)) By the time the OR is visited, both the SELECTs have been visited and not optimized and the OR itself hasn't been transformed so we do this transform in the hopes that the new ORs will be optimized. The transform is explicitly disabled for vector-selects until "codegen matures to handle them better".
