IIRC, there were two things I had problems with: (1) the hack to work
around some cfgloop limitations, and (2) another hack that would
explicitly look for unrenamed variables inside a statement.  At the
time, I thought that #2 should be unnecessary, but it's been a while.

Could you post the patch once again?
