Needs of feature that disabling optimization pipeline in runtime

@iritkatriel
This feature is needed for debugging or experimentation when handling optimized bytecode.
When I want to take a look at the sequence of bytecodes that is optimized with the specific pipeline but not all pipelines, I need to disable several pipelines from https://github.com/python/cpython/blob/30b4e9f9c42493136c58c56fee5553128bb32428/Python/flowgraph.c#L1843-L1851 and rebuild the CPython it's pretty painful because when I want to change the combination of optimization than I should rebuild CPython every time.

It would be great if there is a way to disable specific optimization pipelines at runtime when I want.
Above example is just one specific case and sometime I want to disable all _PyCfg_OptimizeCodeUnit or part of _PyCfg_OptimizeCodeUnit.

This is what I wanted to ask about at the PyCon and will happy to see your opinion about this.

Comienza con Python/flowgraph.c en la canalización _PyCfg_OptimizeCodeUnit mencionada en el issue y sigue cómo se seleccionan sus etapas de optimización durante la ejecución. Define cómo se podrían deshabilitar etapas específicas o toda la canalización sin recompilar CPython y, a continuación, verifica que se puedan inspeccionar distintas combinaciones de optimización según lo solicitado.
