If core-libs folk are okay with this update then I guess we can just handle any test failures if they arise. But I'll run this through our tier 1-3 testing.

> @kelthuzadx I did not see any response to my query about the change in initialization (not load) order. I also remain concerned about introducing cross dependencies between core classes (e.g. String now uses Precondition, so does that impact Precondition using String?) But these are things for the core-libs folk to be concerned about, or not.
