<pre>We currently crash on this:
var [x] = [...y];
Because NodesCodegen thinks that this is a direct binding. It's not, because we cannot directly generate bytecode for "...y". This is a unique property of spread expressions, so its sufficient to just bail out of direct binding if we see a spread expression.</pre>
