Igor Canadi	8b3379dc0a	Implementing DynamicIterator for TransformRepNoLock ... Summary: What @haobo done with TransformRep, now in TransformRepNoLock. Similar implementation, except that I made DynamicIterator a subclass of Iterator which makes me have less iterator initializations. Test Plan: ./prefix_test. Seeing huge savings vs. TransformRep again!

Igor Canadi	be96f2498e	TransformRep - use array instead of unordered_map ... Summary: I'm sending this diff together with https://reviews.facebook.net/D13881 because it didn't allow me to send only the array one. Here I also replaced unordered_map with just an array of shared_ptrs. This elminated all the locks. I will run the new benchmark and post the results here.
