[PATCH] D18656: [SimplifyLibCalls] Strip dead code in printf() transformations

[Davide Italiano via llvm-commits]

I assume that might be a problem.
This change is NFC because the first expression always evaluate to true so we never care about the !Res case even prior to this change. In case we hit a case you describe I'll be more than happy to fix but I think the possibility of an environment defining printf() and not putchar() is very remote anyway.
