It would probably be more straightforward to define a "none vs. anything"
getter instead `isSignReturnAddressHardenWithLoadReturnAddress` and use
something like this
```cpp
if (LangOpts.isSignReturnAddressHardenEnabled()) {
TargetInfo::BranchProtectionInfo BPI(LangOpts);
getModule().addModuleFlag(
llvm::Module::Error, "sign-return-address-harden",
llvm::MDString::get(getLLVMContext(),
BPI.getSignReturnAddressHardeningStr()));
}
