[IronPython] Horrible performance regression of exec on IP2

This is probably because we'll interpret code that is executed using exec.  So anything very computationally heavy will be slow in exec.  Maybe we need a way to disable that.

If you want to see what it'd be like if we weren't interpreting you could use compile() first.

This is just to let you know that I filed a CodePlex issue on this
topic. Please comment (and vote!) there.

In particular, I am interested in the result of execfib.py on .NET.
Current data is on Mono.
