Well, I don't see any difference on my i686-pc-linux-gnu box (actually,
I see a 1.5% speedup).  I guess it's still possible my patch does
something horrific on the automated-test machine, but I'm thinking I
might not be the culprit.  I'll try to find some cycles tomorrow to help
narrow this down further, since it is such a serious regression.

Showed up on x86_64-linux-gnu, not i686-linux-gnu. You can use my machine if you'd like to test :)
