Zdenek, any chance that your aliasing oracle can be used to fix these?

Alias oracle could be used for this; but my patch only uses it in loop
optimizers. So some changes to make ccp use it would be necessary.

Should be fixed now, but H-P Nilsson says on IRC that there is a new ICE in
cse.c that could be related. No details yet. I suppose it's mainline, because
the patches for the branches are so much more trivial.

I have a patch for the 4.1 branch that I'm bootstrap-testing now. It doesn't
look like reverting the mentioned patch will fix the problem in mainline,
though, at least for an x86_64-linux-gnu native.

It was the fwprop merge that further disabled the optimization in the trunk.
