--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I'd add this regressed with r229128, and indeed before that change reassoc has
been able to optimize the comparisons, but now it is not.  So, either we defer
the creation of vec_cond_expr until later time, or need to teach at least
reassoc pass about COND_EXPRs and VEC_COND_EXPRs.
