Hi,

In CardTableBarrierSetAssembler, we sometimes need fencing due to the card table being scanned concurrently when using CMS with pre-cleaning. Rather than explicitly checking for those CMS flags in the generic CardTableBarrierSetAssembler class, it is preferrable to check the CardTable scanned_concurrently() property which already precisely reflects that.

Bug: https://bugs.openjdk.java.net/browse/JDK-8202082

Webrev: http://cr.openjdk.java.net/~eosterlund/8202082/webrev.00/

Thanks, /Erik
