* Convert "specials" array to InterpreterFrame struct, adding f_lasti, f_state and other non-debug FrameObject fields to it. * Refactor, calls pushing the call to the interpreter upward toward _PyEval_Vector. * Compute f_back when on thread stack, only filling in value when frame object outlives stack invocation. * Move ownership of InterpreterFrame in generator from frame object to generator object. * Do not create frame objects for Python calls. * Do not create frame objects for generators.
