Based on @vstinner's advice from #20590 (comment)
This assumption already exists in the interpreter: https://github.com/python/cpython/blob/master/Python/ceval.c#L1328
I checked
PyBytes_GET_SIZE(x)directly instead ofPyBytes_GET_SIZE(x)/sizeof(_Py_CODEUNIT)just like ceval, since presumably the smallest size of 1 for_Py_CODEUNITwould still allowco_codeto be fully indexable with an int.
