================
Comment at: llvm/lib/Transforms/Scalar/GuardWidening.cpp:479
+    // If one of successors ends with deopt, another one is likely.
+    if (IfTrue->getPostdominatingDeoptimizeCall())
+      return IfFalse;
----------------
Crazy compile time heuristic. I guess that IfFalse terminates with deopt is more likely. So just re-order them.
