6787254: Work queue capacity can be increased substantially on some platforms Summary: Increased the default and maximum size of the CMS marking stack and the size of the parallel workers' work queues in 64-bit mode. The latter was accomplished by an increase in the width of the Taskqueue's Age struct and its Tag field in 64-bit mode. Reviewed-by: jmasa, tonyp
