* gh-130740: Move some `stdbool.h` includes after `Python.h` (#130738)Hugo Beauzée-Luyssen2025-03-021-3/+2
| | | | | Move some `#include <stdbool.h>` after `#include "Python.h"` when `pyconfig.h` is not included first and when we are in a platform-agnostic context. This is to avoid having features defined by `stdbool.h` before those decided by `Python.h`.

| | | | | | | | | | | | | | | | | | | | | | CFG (#129426) Codegen phase has an optimization that transforms ``` LOAD_CONST x LOAD_CONST y LOAD_CONXT z BUILD_LIST/BUILD_SET (3) ``` -> ``` BUILD_LIST/BUILD_SET (0) LOAD_CONST (x, y, z) LIST_EXTEND/SET_UPDATE 1 ``` This optimization has now been moved to CFG phase to make #128802 work.
