--- Comment #34 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So, could we in SCCVN recognize similarly to maybe_optimize_range_tests
inter-bb && and || tests at the end stored through PHI into an SSA_NAME without
side-effects in between and handle it (hash it and compare) as if it was
actually using && or || (or & and | ?)?
