The ES2016 draft modifies the semantics of RegExpBuiltinExec to infer "global" and "sticky" using the regular expression object's [[OriginalFlags]] internal slot [1]. Update the algorithm accordingly. This change removes two observable operations. An existing regression test relied on one of these operations (accessing the `global` property) during the evaluation of `RegExp.prototype[@@replace]`. Update the regression test to use a different mechanism to assert the same semantics. [1] tc39/ecma262#494
