[New-bugs-announce] [issue27956] optimize dict_traverse a bit

New submission from Benjamin Peterson:

dict_traverse shows up a lot on statistical profiles of Python programs. This is not surprising since Python programs have lots of dicts. There isn't a huge amount of room for optimization here, but we can avoid some memory indirection. This patch saves a few percent of time through this function in my measurements.
