Tired by deprecation message for unary operators on 8/16 bit vars ? A simple solution

[Basile B.]

I don't know if this is a bug but this works:

```
module runnable;

struct Byte { byte value; alias value this;}

void main()
{
     {Byte b; auto c = ~b;} // no message
     {byte b; auto c = ~b;} // deprecation...
}
```
