bee09aecc2 Issue #29368: The extend() method is now called instead of the append() 
method when unpickle collections.deque and other list-like objects.
This can speed up unpickling to 2 times.

b110dad9ab Initialize variables to fix compiler warnings 
Warnings seen on the "AMD64 Debian PGO 3.x" buildbot. Warnings are false
positive, but variable initialization should not harm performances.

55ba38a480 Use _PyObject_CallMethodIdObjArgs() 
Issue #28915: Replace _PyObject_CallMethodId() with
_PyObject_CallMethodIdObjArgs() in various modules when the format string was
only made of "O" formats, PyObject* arguments.

_PyObject_CallMethodIdObjArgs() avoids the creation of a temporary tuple and
doesn't have to parse a format string.

7bfb42d5b7 Issue #28858: Remove _PyObject_CallArg1() macro 
Replace
   _PyObject_CallArg1(func, arg)
with
   PyObject_CallFunctionObjArgs(func, arg, NULL)

Using the _PyObject_CallArg1() macro increases the usage of the C stack, which
was unexpected and unwanted. PyObject_CallFunctionObjArgs() doesn't have this
issue.

3b73ea1278 Issue #28701: Replace PyUnicode_CompareWithASCIIString with _PyUnicode_EqualToASCIIString. 
The latter function is more readable, faster and doesn't raise exceptions.

AttributeError and ValueError in some cases.

ad8c83ad6b Avoid inefficient way to call functions without argument 
Don't pass "()" format to PyObject_CallXXX() to call a function without
argument: pass NULL as the format string instead. It avoids to have to parse a
string to produce 0 argument.

b98b927e72 _pickle: remove outdated comment 
_Pickle_FastCall() is now fast again!

The optimization was introduced in Python 3.2, removed in Python 3.4 and
reintroduced in Python 3.6 (thanks to the new generic fastcall functions).
