Bug 1480390: Move ForOfIterClose logic inside TryNoteIter r=tcampbell This patch was intended to be a pure refactoring of existing code with no side-effects, moving the logic for handling for-of/for-of-iterclose trynotes inside TryNoteIter to avoid duplicating logic in all users of TryNoteIter. However, it turns out that there was a subtle preexisting bug in TryNoteIter that is fixed by the refactoring. Specifically, the logic to skip from a for-of-iterclose to its enclosing for-of must run before the logic to skip trynotes based on stack depth. Otherwise, the stack depth code may filter out the enclosing for-of (see the attached test case for an example) and we will skip too many try-notes.
