This PR contains all the changes in #989. It also replaces PR #1463, which has been retired.
Some background: When Rex created 989, he used draft-v7 as the base. However, during the v8 work the affected subclause, 13.9.5 "The foreach statement," was subsequently split into 3 subclauses, and text was moved around, changed, and augmented due to the addition of the async streams and using declarations features. Then when Bill pushed 989 into 1463, things got confused with unchanged text being reported as new, and Rex's new text going in the wrong place.
Reviewers: The changes made by this PR were done without consideration of any impact the v8 features async streams and using declarations might have. As such, see if these changes are impacted by 13.5.3, "await foreach."
