There is a call to walk_tree inside of analyze_function that needs to be rewritten because it expects high gimple. It needs to be wrapped in a loop over the basic blocks.

This will cause you to miss a bunch of side effects that in turn will cause you to generate bad code for clobbers.

This code has been tested on i686-linux and power-pc-darwin.

This patch was approved by Jan and has been checked in by me.
This also breaks the cfg inliner again somehow.  Something is
being miscompiled.
Honza, when I have it working again I'm going to commit it. I'm
pretty sick of spending more time on fixing things that break
than on finally doing the cleanups I want to do.
