This patch (r254590) means that we now skip:
gcc.dg/vect/vect-33.c -flto -ffat-lto-objects
scan-tree-dump-times vect "Alignment of access forced using
versioning" 1
gcc.dg/vect/vect-33.c scan-tree-dump-times vect "Alignment of
access forced using versioning" 1
on armeb-none-linux-gnueabihf --with-fpu=neon-fp16

This is because of the change in vect64, which used to give a
different result on arm depending on the endianness.

I think that's not a big deal, but I thought I should mention it.
