Description

'java -help', 'java -X' output is very poor in comparison with RI.

Help options give very little information and it make worse Harmony usability.

It looks like existing print_generic_help() and print_help_on_nonstandard_options() from vmcore/src/init/parse_arguments.cpp are not used.

Similar issue HARMONY-3876 was closed recently,
but it looks like it was partially fixed: only returning value was corrected.
