The motivation here is that Unordered has now acquired a dependency
on SmartPtr, just for those primitives, which is seen as undesirable.

Putting them somewhere else, such as Thread, solves nothing, as a
dependency on Thread for those is much worse.

The alternative to moving them to Core is Unordered containing its own
local copy.
