> Simplify {{SemanticAnalyzer}} by:
>  - Remove dead code
>  - Simplify returning statements
>  - Use interfaces types for parameters/fields/variables where it is straightforward to
migrate
>  - Make visibility stricter where it is possible
>  - Check logging to use parametrised logging
>  - Removing unnecessary keywords (e.g.: {{static}})
>  - Some code part could be simplified by using Java 8 features
> I think this is crucial step as this class already contains 15000+ lines of code which
is screaming for splitting into more reasonable classes.
