[loop-interchange] Move tests to use remarks
Checking the remark message if interchange did or didn't happen is more straight forward than checking the full IR for these cases. This comment was also made when I moved some tests away from relying on debug builds in change #116780, and this is a prep step for #119345 that is going to change these steps.
