Reviewers: rossberg,
Message:
PTAL. The change to the AST is kinda nasty but seemed to be the smallest

I could make to do the right thing (namely, shortcutting the loop if the
iterable is null or undefined, and otherwise binding the iterator to
iterable[@@iterator]()).
Description:
For-of calls [Symbol.iterator]() on RHS to get iterator
