RFR: JDK-8151604: Rely on options range checking rather than explict checks

[Bengt Rutisson]

Hi everyone,

Could I have a couple of reviews for this change?

http://cr.openjdk.java.net/~brutisso/8151604/webrev.00/
https://bugs.openjdk.java.net/browse/JDK-8151604

With the new range checking in the argument parsing we don't need to 
have explicit checks in the code to handle invalid arguments.

Thanks,
Bengt
