Both tests contain misaligned accesses and cannot be vectorized on targets that
have no misalignment support, like ia64. So, I think, the tests should just
fail:

They worked before r175009, because the tests didn't take into account vectors
of two ints, and all the accesses were aligned unintentionally.
Could you please verify that the above patch fixes the failures?
Thanks,
Ira

Yes, the patch in comment #2 fixes the failures on IA64.
