================
Comment at: lib/Transforms/Instrumentation/IndirectCallPromotion.cpp:877
+  // scale up the counts properly (and there is no profitable transformation).
+  if (TotalCount == 0)
+    return false;
----------------
Or change it to 

if (TotalCount < MemOpCountThreshold)
 return false; 

and move this check before the actual count check.
