[issue36937] New _PyObject_MakeTpCall() function

[Jeroen Demeyer]

New submission from Jeroen Demeyer <J.Demeyer at UGent.be>:

Add a new private function

PyObject *_PyObject_MakeTpCall(PyObject *callable, PyObject *const *args, Py_ssize_t nargs, PyObject *keywords)

to call "callable" using tp_call, but with arguments given using the FastCallKeywords or FastCallDict convention (both are allowed, see also https://github.com/python/peps/pull/1038).

The code is not new, it's essentially moving the tp_call case out of _PyObject_FastCallKeywords() and _PyObject_FastCallDict().

This was first proposed (as public API under the name PyCall_MakeTpCall) for PEP 590 but it makes sense to do this independently.
