Subject: [PATCH] fix(benchmarks): remove reference to
 String.prototype.contains()

https://github.com/tc39/tc39-notes/blob/master/es6/2014-11/nov-18.md#51--44-arrayprototypecontains-and-stringprototypecontains

removed String.prototype.contains() from standard, and is not
implemented in most runtimes (SpiderMonkey still being an exception).

Closes #3570
