Hi,
The loops in gcc.dg/vect/vect-peel-3.c and vect-peel-4.c have memory
accesses with different misalignment values that cannot all be aligned
by peeling. Therefore, these tests are not supposed to get vectorized
on vect_no_align targets. This patch xfails the vectorization for such
cases.
Tested on powerpc64-suse-linux and by Steve on IA64.
Committed as obvious.

testsuite/ChangeLog:
* gcc.dg/vect/vect-peel-3.c: Expect to fail on vect_no_align
targets.
* gcc.dg/vect/vect-peel-4.c: Likewise.
