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.
