Because we (as well as powerpc?) don't peel for alignment now, thus the change in peeling cost has no impact on AArch64. I still believe interchange (on the basis of distribution) is the correct direction to fix this regression (and bring further improvement). Of course, vectorization should be avoided even after interchange on x86.
