--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
replace_phi_edge_with_variable assumes we replace things with the same value,
if the new transform does something different because of the _uses_ of the
value then it has to make sure to not copy range info in that function (add
another argument to it?)
