Per this thread http://forum.dlang.org/post/jtlj1k$1fdj$1@digitalmars.com , it
was decided to try and go the path of removing opEquals, opCmp, toHash, and
toString from Object, as they don't need to be there, and the fact that they're
there is causing issues with attributes such as const ( issue# 1824 ).

This issue is specifically for opCmp so that any work towards making it
unnecessary and removing it can be referenced here, whereas the other 3 have
separate bugzilla entries, as the work for them isn't necessarily related to
each other. opEquals, opCmp, and toHash in particular may require substantial
work to be done on the built-in AAs before they can actually be removed from
Object, as the AA implementation is not currently templated like it should be.

Relevant discussion on how to transition away from having these functions on
Object (the thread got broken up a bit - probably by the mailman bug):

http://forum.dlang.org/post/mailman.214.1369617617.13711.digitalmars-d@puremagic.com
http://forum.dlang.org/post/mailman.280.1369712394.13711.digitalmars-d@puremagic.com

The key suggestion is to change the compiler so that those 4 functions can be
free functions in object_.d, similar to how the compiler already does special
stuff for == rather than simply calling Object's opEquals.
