rustdoc: the pointer docs currently render no less than four separate types in a single main "Methods" list

[slightlyoutofphase]

See here.

This was frankly always somewhat confusing even when it amounted to solely the sometimes-identically-named *const T and *mut T methods, but has recently become IMO borderline unnavigable due to the further addition of the methods from *const [T] and *mut [T].

If at all possible, it seems like it would ultimately be good overall to get rustdoc rendering "primitives" in the same separate manner that it does user-defined structs.
