Rob Wu 44025a3ec1 Explicitly state intended support in compatibility.js
Add comments with supported browser versions where missing.

Method:
- Use MDN compat tables if available.
- Otherwise test in Chrome (31+) otherwise.
  (the Chrome Web Store does not update older versions of
   Chrome, so probably nobody is interested in even older
   versions, even though there is an existing comment for
   Chrome<29 at `document.currentScript`).
