[PATCH] PR/19067


This ICE is caused because tree level if-conversion did not produce valid CFG. Patch to fix this is already in TCB branch.

http://gcc.gnu.org/ml/gcc-patches/2004-12/msg00514.html

I quickly verified that it fixes these two test case failures on mainline after I added dominator and dce pass before loop optimization pass as per Zdenek's patch in PR.

I just stared full bootstrap and complete dejaGNU run. OK to move this patch to mainline if it succeeds?

Thanks
