There is an assertion introduced in YIELD_VALUE to check the opcode. However, when the line is being traced, the opcode would be INSTRUMENTED_LINE or INSTRUMENTED_INSTRUCTION and _PyOpcode_Deopt won't convert it back.

We can be more precise here to get the exact base opcode of the instruction, but that would probably introduce extra code outside of the assertion (the code object and the index is needed).

I think in this case, adding the two instrumentation opcode is good enough because the assertion is well covered in non-tracing mode.

Thanks for the fix! I'll merge now so the quality of beta 1 is epsilon higher.
