regression test - 8029255

Hello.

http://mail.openjdk.java.net/pipermail/hotspot-gc-dev/2013-December/009012.html

Would you please write regression test or justify it's absence? Probably 
label "noreg-hard" is appropriate for this case since it looks like 
refactoring without external behavior change?

Also "noreg-cleanup" can fit this case. You know it better.

Please, find manual here: http://openjdk.java.net/guide/changePlanning.html
