Summary:
llvm/lib/ExecutionEngine/Orc/Layer.cpp:53:12: warning: returning address of local temporary object [-Wreturn-stack-address]
In
```
StringRef IRMaterializationUnit::getName() const {
[...]
return TSM.withModuleDo(
[](const Module &M) { return M.getModuleIdentifier(); });
```
`getModuleIdentifier()` returns a `const std::string &`, but the implicit return type
of the lambda is `std::string` by value, and thus the returned `StringRef` refers
to a temporary `std::string`.
Detect by annotating `llvm::StringRef` with `[[gsl::Pointer]]`.
