[issue1717] Get rid of more refercenes to __cmp__

[Raymond Hettinger]

Raymond Hettinger <rhettinger at users.sourceforge.net> added the comment:

Moving cmp() somewhere other than builtins is not progress.  IMO, it
needs to die off and the concept of it needs to disappear completely. 
Code is better without it.  Three-way comparisons are PITA to use --
their only virtue is as an optimization in the few cases where one
three-way test is cheaper to compute than two two-way tests.

The goal for 3.0 was to have one way to do it and thereby simplify the
language.  Tucking it away in a module or writing a new decorator
defeats the purpose.  It simply should die and go away.
