  Tested x86_64-linux. Pushed to trunk.

The Cpp17Allocator requirements say that an allocator's pointer and
const_pointer types must meet the Cpp17RandomAccessIterator
requirements. That means our PointerBase helper for defining fancy
pointer types should support the full set of relational operators.

libstdc++-v3/ChangeLog:

	* testsuite/util/testsuite_allocator.h (PointerBase): Add
	relational operators.
