This benchmark was run with LTO+PGO. It seems like PGO produced less efficient machine code with the patch. Maybe a missed optimization.

Oh, I just realized that I announced that objects with a __call__() are faster, but it's not the case yet! Such object still gets slot_tp_call() as tp_call which isn't a fastcall!
