Fixed additional patterns: - _PyOpcode_* → _TyOpcode_* (all opcode metadata) - _PyUOpName → _TyUOpName - _PyFunction_* → _TyFunction_* - _PyListIterObject → _TyListIterObject - _Py_T_OBJECT → _Ty_T_OBJECT - Py_BEGIN_ALLOW_THREADS, Py_END_ALLOW_THREADS → Ty_* - PyDoc_STRVAR, PyDoc_STR → TyDoc_* - PyInterpreterState, PyThread_*, PyTime_t → Ty* - PyStructSequence_* → TyStructSequence_* - PyLockStatus → TyLockStatus - PyVarObject_HEAD_INIT → TyVarObject_HEAD_INIT - PyBaseExceptionObject → TyBaseExceptionObject - Fixed _PyExc_ → _TyExc_ in exception macros Build is progressing further.
