[New-bugs-announce] [issue37207] Use PEP 590 vectorcall to speed up calls to range(), list() and dict()

[Mark Shannon]

New submission from Mark Shannon <mark at hotpy.org>:

PEP 590 allows us the short circuit the __new__, __init__ slow path for commonly created builtin types.
As an initial step, we can speed up calls to range, list and dict by about 30%.
