Hi,
I completely forgot I still had this patch out as well, I grouped it
together with the unrolling because it was what motivated the change,
but it is actually wider applicable and can be reviewed separately.

Hi,
This patch changes the order in which we check outside and inside
costs for epilogue loops, this is to ensure that a predicated epilogue
is more likely to be picked over an unpredicated one, since it saves
having to enter a scalar epilogue loop.
gcc/ChangeLog:
* tree-vect-loop.c (vect_better_loop_vinfo_p): Change how
epilogue loop costs are compared.
