<pre>
    We should migrate away from `report_fatal_error` as it has been "soft" deprecated in `llvm/include/llvm/Support/ErrorHandling.h`:

```
/// @deprecated Use reportFatalInternalError() or reportFatalUsageError()
/// instead.
[[noreturn]] void report_fatal_error(const char *reason,
 bool gen_crash_diag = true);
```

and in `llvm/include/llvm/Support/Error.h`:

```
/// @deprecated Use reportFatalInternalError() or reportFatalUsageError()
/// instead.
[[noreturn]] void report_fatal_error(Error Err, bool gen_crash_diag = true);
```

Once we are done, we should remove the bits to disable `-Wno-documentation-deprecated-sync`. (#138909)
