Merge r174019 - Web Inspector: Type Token View shows type information…

… on hover when it shouldn't

Reviewed by Brian J. Burg.

TypeTokenView should only show type information when there is
more than one primitive type or more than zero objects types.
This fixes a bug in checking the length of object types.

* UserInterface/Views/TypeTokenView.js:
(WebInspector.TypeTokenView.prototype._shouldShowPopover):
