0f7b0b397e bpo-29735: Optimize partial_call(): avoid tuple (#516)
* Add _PyObject_HasFastCall()
* partial_call() now avoids temporary tuple to pass positional
  arguments if the callable supports the FASTCALL calling convention
  for positional arguments.
* Fix also a performance regression in partial_call() if the callable
  doesn't support FASTCALL.

457fc9a69e Issue #27137: align Python & C implementations of functools.partial
The pure Python fallback implementation of functools.partial
now matches the behaviour of its accelerated C counterpart for
subclassing, pickling and text representation purposes.

Patch by Emanuel Barry and Serhiy Storchaka.
