================
Comment at: lib/CodeGen/ImplicitNullChecks.cpp:600
     DefReg = MI->defs().begin()->getReg();
-    assert(distance(MI->defs()) == 1 && "expected exactly one def!");
+    assert(size(MI->defs()) == 1 && "expected exactly one def!");
   }
----------------
Can you just change this to NumDefs == 1? The end for defs() is calculated with MI->getDesc().getNumDefs() which is what NumDefs is assigned to.
