The FEAT_MOPS memory copy operations need an extra helper routine
for checking for MTE tag checking failures beyond the ones we
already added for memory set operations:
  * mte_mops_probe_rev() does the same job as mte_mops_probe(), but
    it checks tags starting at the provided address and working
    backwards, rather than forwards
