The FEAT_MOPS instructions need a couple of helper routines that
check for MTE tag failures:
* mte_mops_probe() checks whether there is going to be a tag
error in the next up-to-a-page worth of data
* mte_check_fail() is an existing function to record the fact
of a tag failure, which we need to make global so we can
call it from helper-a64.c
