I've confirmed that that problem is remained after reverting
r119706 changes of cse.c. So it may be another problem, though
it might produce a wrong stage 1 compiler for mipsel-linux and
end up with the ICE in stage 2.
In the mipsel-linux case, we ended up with a diamond region where the
jump in the IF-block was folded, so that we could extend the path
along one of the diamond's arms with the JOIN-block. This could
happen because cse_main traversed the basic blocks in DFS order
instead of in topological order. I have just posted a hopeful fix for
this.
