If Python is compiled with gcc -O3, gdb is unable to get the f argument of PyEval_EvalFrameEx(). It is possible to retrieve "f" from the caller, PyEval_EvalCodeEx().
Attached patch tries to implement this idea and enable more test_gdb tests on optimized Python.
The patch has a problem because some tests fails if Python is not optimized (Python compiled in debug mode).
--
The patch fix other minor bugs in libpython.py related to optimized Python.

It does not always work, but it works sometimes, so it's better to try :-)
I applied my fix to Python 2.7, 3.2 and 3.3. lipython.py of Python 2.7 is outdated, it should be resynchronized with the one of Python 3.3. I will do that later and in another issue.
