This should actually return an instance of DILError. Something like:
```suggestion
llvm::Error CreateDiagnosticError(DILError::ErrorCode code, llvm::StringRef
text, const std::string &message,
uint32_t loc, uint16_t err_len) {
DiagnosticDetail detail = /*the same as before*/;
return llvm::make_error<DILError>(code, detail, ???);
```
