[Bug tree-optimization/22481] New: ICE in extract_constrain_insn_cached, at recog.c:2000 with -O3 -fpeel-loops

["micis at gmx dot de" <gcc-bugzilla at gcc dot gnu dot org>]

When I compile ace542 with the actual snapshot of gcc41 I get an ICE when I 
use -O3 -fpeel-loops.

The ICE occurs first with snapshot gcc-4.1-20050611, snapshot gcc-4.1-20050604 
works.
