    [Hexagon] Add defaulted operator= to classes with defaulted copy ctor
    
    This avoids deprecation warning:
    ```
    warning: definition of implicit copy assignment operator for 'AddrInfo'
    is deprecated because it has a user-declared copy constructor
    [-Wdeprecated-copy]
    ```
    
    This fixes https://github.com/llvm/llvm-project/issues/57229
```
