Lint option: Many defined variables with the same type should become LIKE(x)

E.g.

```
Dcl-S name char(25);
Dcl-Ds stuff qualified;
name char(25);
initials char(3);
End-Ds;
```

Should be

```
Dcl-C NAME_LENGTH 25;

Dcl-S name char(NAME_LENGTH);
Dcl-Ds stuff qualified;
name char(NAME_LENGTH);
initials char(3);
End-Ds;
```

Though, not sure how to force this. We'd need to quick fix to handle this
