[jira] Updated: (THRIFT-675) Generated findByValue() should just switch on value instead of mapping

This goes back to switch statements. How's it do in your benchmarks?

> Generated enum classes currently use a map in findByValue() to go from an integer value to an enum.
> Instead of using a map, it is faster to simply switch on the value with a default case returning null.
> On some benchmarks I ran, this saved 7% of deserialization time.
