Sanjay Patel 6d8b694072 [InstCombine] avoid crashing on attribute propagation ... In https://llvm.org/PR48810 , we are crashing while trying to propagate attributes from mempcpy (returns void*) to memcpy (returns nothing - void). We can avoid the crash by removing known incompatible attributes for the void return type. I'm not sure if this goes far enough (should we just drop all attributes since this isn't the same function?). We also need to audit other transforms in LibCallSimplifier to make sure there are no other cases that have the same problem.
