There is a benchmark for the class method `Buffer.compare()` but not for the instance method `buf.compare()`. This adds that benchmark. I used this to confirm a performance regression in an implementation I was considering. While the implementation was a bust, it does seem like the benchmark is worthwhile. The benchmark is nearly identical to the existing `Buffer.compare()` benchmark except, of course, that it calls `buf.compare()` instead.

There was a problem hiding this comment.
Please insert code to force optimization of b0.compare before starting the benchmark. Take a look at some of the other (e.g. path) benchmarks to see how to do this.

This and the other instance below should instead be b0.compare(b1);
