--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So this won't work even though it is the right thing to do because when we are
folding `if (a != 1)` and a is defined by a comparison, we want to get back the
comparison.
Now you could say this is problem in how we fold GIMPLE_COND but it is what it
is right now.
