Report RUN command statements that are non-deterministic like if and case statements
**Describe the Feature**
Currently, the report notices just says that if, case and for statements are unrecognizable. It would be nice to add notices for non-deterministic branching statements like if and case statements as you could only know the status of the branch at build time.

**Implementation Changes**
The new shell script parser produces a dictionary that will identify if and case statements. We could just look at this object and extract the if and case statements to create notices for them.
