JDK 9 RFR of JDK-8151763; Use more informative format for problem list

[joe darcy]

Hello,

As Jon Gibbons has noted off-list, the problem list entries can directly 
include the bug number associated with the test in question, enabling 
better reporting. This format should be used rather than the current 
convention of putting the bug number in a comment.

Please review the webrev to adopt the revised format for the problem list:

     http://cr.openjdk.java.net/~darcy/8151763.0/

I've verified jtreg produces the same test list with the old and new 
versions of the problem list.

Thanks,

-Joe
