RFR(S): 8198608: Improvements to command-line flags printing

[Schmidt, Lutz]

Dear all,

may I please request reviews for this small enhancement:

Bug:     https://bugs.openjdk.java.net/browse/JDK-8198608
Webrev:  http://cr.openjdk.java.net/~lucy/webrevs/8198608.00/

The code in Flag::print_on() so far wasn’t very easy to understand. Changing the layout of what was printed required some deep thinking. I hope that, with my changes, future modifications will be easier.

The before/after output of -XX:+PrintFlagsFinal is identical, except for those argument names which are longer than expected. In that case, the new version prints one space less, which is by intention.

Thank you!
Lutz
