benchmark: reformat code for clarity

Some of the benchmark code can be a little dense. Not *very* hard to read but perhaps harder than it needs to be. These changes (many of them whitespace-only) hopefully improve readability. There are also a few cases of `assert.equal()` that are changed to `assert.strictEqual()`.
