This set of changes seems to have caused the regression:
http://gcc.gnu.org/ml/gcc-cvs/2004-10/msg01561.html
Or more specifically
http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/gcc/tree-ssa-loop-ivopts.c.diff?cvsroot=gcc&r1=2.20&r2=2.21
If I re-enable walking all of the candidates (as opposed to just the "important"
ones" I get back the optimizations that were present before and this test case
will pass again.
