RFR: 8326333: jshell <TAB> completion on arrays is incomplete [v2]

[Jan Lahoda]

> Inside jshell, arrays don't show `Object` method in array code completion, i.e.:
> 
> jshell> String[] arr = null;
> arr ==> null
> 
> jshell> arr.<code-completion-here>
> 
> 
> will only show `length`. This patch adds `j.l.Object` methods to the suggestions for arrays.
