There are a couple of instances where the debug information has not been propagated to the new overflow/saturation instructions:
```
BinaryOperator *NewResult = BinaryOperator::Create(
WO->getBinaryOp(), WO->getLHS(), WO->getRHS(), "", WO->getIterator());
.....
for (auto *U : WO->users()) {
if (auto *EVI = dyn_cast<ExtractValueInst>(U)) {
if (EVI->getIndices()[0] == 1)
EVI->replaceAllUsesWith(ConstantInt::getFalse(WO->getContext()));
else {
assert(EVI->getIndices()[0] == 0 && "Only two possibilities!");
EVI->replaceAllUsesWith(NewResult);
}
```
```
BinaryOperator *BO = BinaryOperator::Create(
SI->getBinaryOp(), SI->getLHS(), SI->getRHS(), SI->getName(), SI->getIterator());
if (SI->isSigned())
BO->setHasNoSignedWrap();
else
BO->setHasNoUnsignedWrap();
SI->replaceAllUsesWith(BO);
```
