[issue5730] setdefault speedup

Dan Schult added the comment: Benchmarks: Upon trying cooked up examples, I do not notice any speedup beyond 5-10%. Seems like function calling time swamps everything for small examples with fast hashes. I don't have a handy dandy example with long hash times or long lookup times. That's what
