Thanks for detangling the '-XX:Flags=' options support from the
rest of the more recent (and modern?) cmd options changes. That
will make it easier to (hopefully) deprecate (and eventually
remove) the '-XX:Flags=' option...

If we decide not to remove the '-XX:Flags=' option, then at
least we don't have to carry its baggage through all the
new function calls...
