Updating benchmarks for recent cuDNN v6

[crockpotveggies]

cuDNN v6 is now released and there are clear improvements. How can I go about updating these numbers (and adding more frameworks)? Is it best to just submit a PR with README tables updated? Or did you have different plans for new cuDNN versions?

So far I've got the following for TensorFlow:

i dont have plans to benchmark / maintain these tables. If you send a PR with README tables updated for all the frameworks, i'm happy to merge.
