RFR: 8235876: Misleading warning message in java source-file mode [v2]

[Adam Sotona]

> Execution of  `java --source 7 Test.java` displays following warning: 
> `warning: [options] To suppress warnings about obsolete options, use -Xlint:-options.` 
> 
> However use of `-Xlint:-options` is not allowed and so it proposes an invalid suggestion.
> 
> This is yet another case of "too much information" provided to user in source-file mode. 
> Target audience of source-file mode are Java beginners with very simple cases.
> Many options are not available in source-file mode and so this patch disables also related options warnings.
> 
> The case is similar to JDK-8268869
> 
> Patch adds `-Xlint:-options` into the list of default javac options in source-file mode.
> Relevant test is also provided.
> 
> Thanks,
> Adam
