================
Comment at: lib/CodeGen/GlobalISel/InstructionSelect.cpp:75-78
+      if (MII == Begin)
+        ReachedBegin = true;
+      else
+        --MII;
----------------
nit: How about doing the --MII in the for statement?

  for (auto MII = ...; !ReachedBegin; --MII) {
    ...
    ReachedBegin = MII == Begin;
    ...
  }
