LG with a nit.



================
Comment at: lib/Transforms/InstCombine/InstCombineCompares.cpp:979-980
         return replaceInstUsesWith(I, // No comparison is needed here.
-                             Builder.getInt1(ICmpInst::isTrueWhenEqual(Cond)));
+          Constant::getIntegerValue(I.getType(),
+                                    APInt(1, ICmpInst::isTrueWhenEqual(Cond))));
 
----------------
There are all these `Constant::get()`/`ConstantInt::get()` overloads that don't require `APInt`.
Have you checked they aren't sufficient?
