        Description

        The thread claim parity is used to parallelize the scanning of root in the JavaThreads. This was placed in SharedHeap, but used by the Thread class (Threads::possibly_parallel_oops_do()). Moving this claiming state into the Thread class will collect the state information and the usage in one place. It will also anther step towards eventually being able to remove SharedHeap.
