ping2 [patch] Autovectorization loop versioning for data alignment

[Dorit Naishlos]

This bit in the patch should fix PR23350:

+  /* Often peeling for alignment will require peeling for loop-bound,
which in
+     turn requires that we know how to adjust the loop ivs after the loop.
*/
+  if (!vect_can_advance_ivs_p (loop_vinfo))
+    do_peeling = false;


We're also waiting on this patch to synch up the branch with mainline.

thanks,

dorit
