[IronPython] Horrible performance regression of exec on IP2

[Dino Viehland]

Shri just suggested (off-line and on the bug) that we detect non-straight line code and actually compile it.  We used to have logic around to do that so it shouldn't be too hard to bring it back and make this work more as expected :)

Argh, I was using exec as a poor man's macro tool. Exactly
computationally heavy code was roop-unrolled using exec.

You can guess why I was very disappointed...
