7160728: Introduce an extra logging level for G1 logging Summary: Added log levels "fine", "finer" and "finest". Let PrintGC map to "fine" and PrintGCDetails map to "finer". Separated out the per worker information in the G1 logging to the "finest" level. Reviewed-by: stefank, jwilhelm, tonyp, johnc
