[issue34090] Python function call optimization: avoid temporary tuple to pass **kwargs

[STINNER Victor]

Yeah, I recall these issues since I wrote them :-D

The fix for bpo-29318 was to document that we must copy the kwargs dict ;-)

But this issue is not about the copy of the kwargs dict, but about two useless conversions: kwargs dict -> kwnames tuple -> kwargs dict.
