[issue30907] speed up comparisons to self for built-in containers

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I don't have any objections to closing this. The net benefit is contradictory, the maintenance cost is not zero. In many performance important cases (dictionary lookup, searching in sequences) the identity already is checked before calling the comparison method.

Maybe it is worth to remove the fast patch from slice_richcompare() or speed up the general case, but this is a different issue.
