2018-06-08Fix issue with resolveNodes() not found off global proxy object.Tom Sepez
We used to assume that a global proxy object could be distinguished by it not having two internal fields, but that invariant isn't correct. Instead, flag it as such so the block of code at line 126 will check the prototype to find an actual object. Squeeze some bytes out of the tags while were at it, no reason for them to be wide. Also remove GetGlobalObjectFromContext() helper, for transparency into what's really going on in v8. This then shows a needless retrieval of an object we already have in one case.
