It turns out that some old polyfill library uses RegExp.prototype.flags as a way of feature testing. It's not clear how widespread this is. For now, as a minimal workaround, we can return undefined from getters like RegExp.prototype.global when the receiver is RegExp.prototype. This patch implements that strategy but omits a UseCounter to make backports easier.
