Summary: Speed-up tp_compare usage

Initial Comment:
This patch tries to optimize PyObject_RichCompare for
the common case of objects with equal types which
support tp_compare. It gives a speed-up of roughly 7%
for comparing strings in a loop.

The patch also gives type objects a tp_compare
function, so that they can make use of the improvement.

The revised patch prefers tp_compare over tp_richcompare in
do_cmp if both are available. It also restores
UserList.__cmp__ from deprecation.
