Start tracing at `JUMP_BACKWARD_NO_INTERRUPT`

Feature or enhancement

Proposal:

We have just added the ability to start tracing at the beginning of functions.
That still leaves yield from and await loops to be run in the interpreter without jitting.
By starting tracing at JUMP_BACKWARD_NO_INTERRUPT we fill that gap.

Before we can do that, there are two problems we need to fix:

• https://github.com/python/cpython/issues/145047 and
• https://github.com/python/cpython/issues/146073

Once those are fixed, this should give us good jit coverage without degrading the quality of the traces.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

Leggi prima le issue 145047 e 146073, poiché questa proposta dipende dalla correzione di entrambe. Poi esamina il tracing e la gestione del JIT di CPython per JUMP_BACKWARD_NO_INTERRUPT, incluso il comportamento esistente del tracing all’inizio delle funzioni. Il lavoro è completato quando i loop yield from e await possono iniziare il tracing in quel punto senza degradare la qualità del trace.
