Fix binary search benchmarks. [ci skip]
Fix doc typo as `_.support.ownLast` is "false" in all but IE < 9. [ci skip]

support.ownLast is "false" in all but IE < 9. I guess a short way to describe that is "none but IE < 9" but having "all but IE < 9" is misleading. As the rest of the support properties (e.g. funcNames) return "true" when you have a browser that fits in the "all" part.
