+        if (OpRHS.getOpcode() == CondRHS.getOpcode() &&
+            (OpRHS.getOpcode() == ISD::BUILD_VECTOR ||
+             OpRHS.getOpcode() == ISD::SPLAT_VECTOR) &&
----------------
I was wondering whether now's the time to add yet another function like `ISD::isBuildVectorOrSplatVector`. Thoughts?
