bmeurer	679d9503cf	[undetectable] Really get comparisons of document.all right now. ... According to https://www.w3.org/TR/html5/obsolete.html#dom-document-all, comparisons of document.all to other values such as strings or objects, are unaffected. In fact document.all only gets special treatment in comparisons with null or undefined according to HTML. Especially setting the undetectable doesn't make two distinct JSReceivers equal.

bmeurer	1b821f2f39	[ic] Unify undetectable abstract equality comparison. ... The treatment of different undetectable objects was inconsistent after the latest changes to the undetectable bit in the maps. Given two different undetectable JSObjects a and b, a monomorphic CompareIC would say false for a == b, while the rest of the system (including the generic case for the CompareIC) would say true. The fix is rather straight-forward: We just go generic on a CompareIC once we see an undetectable JSObject.
