Issue #13628: python-gdb.py is now able to retrieve more frames in the Python traceback if Python is optimized. * delay the lookup of the size_t type, it is not available at startup * The second argument of the PyFrameObjectPtr constructor is optional, as done in other constructors * iter_builtins() and iter_globals() methods of PyFrameObjectPtr returns an empty tuple instead of None if Python is optimized * Fix py-bt to handle correctly "optimized" frames * Frame.get_pyop() tries to get the frame pointer from PyEval_EvalCodeEx() if the pointer is optimized out in PyEval_EvalFrameEx()
