  Log Message:
  -----------
  Add clang::lifetimebound annotation to StringRef constructors. (#113878)

Adding the lifetimebound annotation to the ArrayRef's array constructor
can enable us to detect the following use-after-free issues:

```
llvm::StringRef TestZoneName() {
   char test[] = "foo"; // oops, missing static
   return test; // use-after-free.
}
```

See #113533
