7006113: G1: Initialize ReferenceProcessor::_is_alive_non_header field Summary: Initialize the _is_alive_non_header field of G1's reference processor with an instance of the G1CMIsAliveClosure. This will stop adding reference objects with live referents to the discovered reference lists unnecessarily. Reviewed-by: tonyp, ysr, jwilhelm, brutisso
