  Log Message:
  -----------
  Don't accidentally create MachineFunctions in mir-debugify/mir-strip-debugify

We should only modify existing ones. Previously, we were creating
MachineFunctions for externally-available functions. AFAICT this was benign
in tree but ultimately led to asan bugs in our out of tree target.
