[PATCH] D18900: New pre-isel pass SystemZBRCTLoops

Yes, I started my experiment by copying and modifying until I had a simplest version that seemed to work.
I also think it should definitely be possible to make a target independent version like you proposed.

For SystemZ, this is currently giving mixed results, and I think it will have to wait until the pre-ra scheduler is in place. Thanks for review so far.
