<pre>In r198698, for the purpose of enabling feature testing, I changed the RegExp.prototype flag property getters to always return undefined instead of throwing when "this" is not a RegExp object. However, for the purpose of feature testing, we only need to apply this change for the cases where the getters are called on the RegExp.prototype itself. If called with any other "this" values that is not a RegExp object, they should throw a TypeError as the ES6 spec expects.</pre>
