7112034: Parallel CMS fails to properly mark reference objects
Summary: Enabled reference processing when work stealing during 
concurrent marking

The cause of this bug is that no reference processor is registered with 
the marking closure that is used during work stealing in the concurrent 
mark phase. If we add the reference processor we find the expected 
number of Finalizer objects during concurrent marking.
