[llvm] [NFC][OpenMP] Update a test that was failing on aarch64. (PR #164456)

[Abhinav Gaba via llvm-commits]

https://github.com/abhinavgaba created https://github.com/llvm/llvm-project/pull/164456

The failure was reported here:

https://github.com/llvm/llvm-project/pull/164039#issuecomment-3425429556

The test is checking for the "bad" behavior so as to keep track of it. It could just be updated to check the "good" behavior and marked as XFAIL, but then it would not be as informative.

The update for now is to fix the pointer arithmetic. If that isn't sufficient, we can fall back to doing the above.
