For the fast case we can avoid the instance type check, since the map check covers that. We also don't need to call out to the ToBoolean builtin in general, but just use the BranchIfToBooleanIsTrue logic. Plus in the fast case, we don't know that the JSIteratorResult::done is a boolean, since the map doesn't guard this assumption, so we also need to do a proper BranchIfToBooleanIsTrue in that case.
