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

先阅读 issue 145047 和 146073，因为该提案依赖于这两个 issue 都已修复。然后检查 CPython 对 JUMP_BACKWARD_NO_INTERRUPT 的 tracing 和 JIT 处理，包括现有的函数开始时 tracing 行为。当 yield from 和 await 循环可以在那里开始 tracing，且不会降低 trace 质量时，即视为完成。
