Add missing operator<() to CFX_RetainPtr.
Use std::less<>() rather than a direct ptr1 < ptr2 comparison to be strictly correct in face of unspecified behaviour when ptr1 and ptr2 don't point within the same "object" (e.g. segment of memory on a brain-dead segmented architecture). This will allow their use as keys in maps. Review-Url: https://codereview.chromium.org/2616683002
