[issue29464] Specialize FASTCALL for functions with positional-only parameters

The major part of the patch is generated by Argument Clinic. It is not a pain to rebase it. I prefer to delay pushing the patch until we prove its usefulness, because the cost of this change is not zero. Is it a stopper for issue29465?
