Would it be worthwhile to explore normalizing the G1LogLevel with CMSLogLevel values?

The fix is to add a flush call to G1CollectedHeap::log_gc_footer(). I also noticed that TraceCPUTime destructor does not flush the specified log file and, since it only seems to be instantiated from GC code, it probably should.
