CPU Benchmarks

Originally written by @lxp in Issue #23

Note that

• Benchmark4kEncStupidGCM = OpenSSL through our stupidgcm wrapper,
• Benchmark4kEncGoGCM = Go stdlib.

In recent gocryptfs versions you can run gocryptfs -speed to run the benchmarks and get nicer output.

The tests were run on go version go1.6 linux/amd64 unless noted otherwise.
