[IronPython] patch to enable codeop.py on fepy

[Anthony Baxter]

The following patch makes codeop.py (and therefore stuff that depends
on it, such as code.py) work on IronPython. I needed this for the talk
I did on Thursday, where I had an interactive interpreter example
built on a rough port of Bruce (http://bruce.python-hosting.com)
outputting to SDL. It would be nice if the builtin compile() supported
this flag - I assume there's some support for it, since the
interactive interpreter does the right thing with it. This patch makes
codeop.py "work", but it does cause a slight change in behaviour,
damn.

The docs for compile() don't actually mention this flag - I've logged
an SF bugreport about that.

And yes, I plan to clean up and release the Bruce on
IronPython+sdldotnet code. Not today, though - still recovering from
the conference. :-)
