The vectorizer in the aarch64 case manages to emit a VEC_PERM_EXPR instead
(which is just as efficient).
So, do we want to go for the following (and/or perhaps also restrict the test to
a couple of targets where it works? In my last distro build it failed only
on aarch64-linux, while armv7hl-linux-gnueabi and
{i686,x86_64,powerpc64le,s390x}-linux were fine)?

* gcc.dg/pr96573.c: Instead of __builtin_bswap accept also
VEC_PERM_EXPR with bswapping permutation.
