--- Comment #2 from alalaw01 at gcc dot gnu.org ---
If-conversion will handle the three-arg phi node, if aggressive_if_conv is
true, i.e. if loop->force_vectorize. I believe it's possible to set this using
a #pragma (?), but I haven't managed yet. A question might be whether it's safe
to deal with three-arg phi-nodes when !aggressive_if_conv...
