WebHistory.h exposes two methods (`-orderedLastVisitedDays` and `-orderedItemsLastVisitedOnDay:`) dealing with NSCalendarDate. OS X has deprecated NSCalendarDate. In both of these cases, replacement API dealing with NSDate (over NSCalendarDate) should be added. Eventually, the NSCalendarDate methods should be deprecated.
We’re tracking the deprecations in a separate bug. Retitling this to track adding new API.
