c6944e7edc Issue #28618: Make hot functions using __attribute__((hot)) 
When Python is not compiled with PGO, the performance of Python on call_simple
and call_method microbenchmarks depend highly on the code placement. In the
worst case, the performance slowdown can be up to 70%.

The GCC __attribute__((hot)) attribute helps to keep hot code close to reduce
the risk of such major slowdown. This attribute is ignored when Python is
compiled with PGO.

The following functions are considered as hot according to statistics collected
by perf record/perf report:

* _PyEval_EvalFrameDefault()
* call_function()
* _PyFunction_FastCall()
* PyFrame_New()
* frame_dealloc()
* PyErr_Occurred()

0cae609847 Use PyThreadState_GET() in performance critical code 
It seems like _PyThreadState_UncheckedGet() is not inlined as expected, even
when using gcc -O3.

2edd8a1e2c Issue #27243: Change PendingDeprecationWarning -> DeprecationWarning. 
As it was agreed in the issue, __aiter__ returning an awaitable
should result in PendingDeprecationWarning in 3.5 and in
DeprecationWarning in 3.6.

C99 inline semantics don't work everywhere. (https://bugs.python.org/issue28092)
We don't want these to have external visibility anyway.
