Affected subclause: [iterator.traits]

Change: The specialization of iterator_traits for void* and for function pointer types no longer contains any nested typedefs.

Rationale: Corrects an issue misidentifying pointer types that are not incrementable as iterator types.

Effect on original feature: A valid C++ 2017 program that relies on the presence of the typedefs may fail to compile, or have different behavior.
