ES2016 Draft 2015-10-05

The changes in this draft don't introduce any new semantics. Numerous editorial issues have been fixed and some spec text has been clarified. Details below:

• Added abstract operation SameValueNonNumber. Refactored SameValue and SameValueZero to use SameValueNonNumber. This removes lots of duplicated logic and clarifies exactly how SameValue and SameValueZero differ. (#60)
• Bugzilla bugs fixed: 4526, 4496, 4500, 4498, 4482, 4522, 4492, 4507, 4508, 4436, 4425, 295, 302, 292, 4314, 4395

Additionally, over 100 Bugzilla bugs were closed as being already fixed or otherwise no longer valid against the latest version of the spec. If your bug was closed incorrectly as part of this effort, please re-open it on GitHub!
