RFR: JDK-8264222: Use switch expression in jshell where possible [v3]

[Tagir F.Valeev]

> This change is powered by IntelliJ IDEA quick-fix.
> I also took the liberty to fix C-style arrays in changed files.
> 
> In SourceCodeAnalysisImpl.java:501, I left case PARAMETERIZED_TYPE -> FALSE as a separate switch case, because it had a comment. Better formatting ideas are welcome.
> 
> If you like this, I can provide similar PR in other components as well (e.g. in javac)
