What shall we do with gcc.dg/vect/vect-11.c?

Hi Dorit,

What shall we do with gcc.dg/vect/vect-11.c?  After I fixed PR
tree-optimization/25125, gcc.dg/vect/vect-11.c started failing on some
targets but not on x86_pc-linux-gnu.  If we XFAIL it, we would get
XPASS on x86_pc-linux-gnu.  I am pretty sure that adding -fwrapv will
fix the problem, but that means we are changing the test case.  Shall
we add something like gcc.dg/vect/fwrapv-vect-11.c, remove vect-11.c,
and file a missed optimization PR for vect-11.c?

Any thoughts?
