Ah, this particular fault is because I recently added a new element to MIR files. It would appear that you're using an older version of llc to read the output of a newer llc -- you should be able to just rebuild llc and it will work, or in the worst case, rebase onto a commit more recent than rG9f8544713ad8e57 <https://reviews.llvm.org/rG9f8544713ad8e57fb74cbfce3fbc7fff523e549f>.

Alternately, you can just delete the lines "debugInstrRef:   true" from the tests safely, as you're not testing anything to do with that feature
