[Bug middle-end/17503] [4.0 Regression] Huge performance regression in invalid_mode_change_p

I find it extremely unlikely that the patch mentioned in comment #2 could have
any performance impact, even on code that declares register variables which
should be the only observable functionality change.

Daniel, I wonder whether you could re-run your profiles after reverting my
patch and confirm there's no performance change, i.e. that it's innocent?
