Clean up some useless-super-delegation logic (#5193)

* Clean up some useless-super-delegation logic

In _definition_equivalent_to_call, avoid constructing a tuple and
calling "all" on that. Instead, just check each condition in turn,
terminating as soon as one fails.

In _has_different_parameters_default_value, use a single sentinel value
for a missing default instead of constructing a new one each call. Also
construct the dict of comparators once instead of once each call.
Restructure the logic to be less nested.
