RFR(xs): 8171011: convert some CDS dump time warning and error messages to informational messages which will be printed with -XX:+PrintSharedSpaces

[Calvin Cheung]

Hi Jiangli,

Thanks for your review.

I've updated the webrev: 
http://cr.openjdk.java.net/~ccheung/8171011/webrev.01/

Diff from the previous patch:
< -                                        "--limit-modules", // cannot 
use at dump time
< +                                        "--limit-modules", // ignored 
at dump time

thanks,
Calvin
