--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This is the typical case of value range info being more precise during vrp pass
(where we have ASSERT_EXPRs) rather than elsewhere (where we don't have them
and pin_3 here is set before the condition).  Supposedly the planed on demand
value range stuff could help there, but I have no idea for ETA on that.
