Summary: Handlize MemoryUsage klass oop in createGCInfo routine
Reviewed-by: tonyp, fparain, ysr, jcoomes

Summary: GCNotifier::pushNotification() references GCMemoryManager::_last_gc_stat but is called from GCMemoryManager::gc_end() before GCMemoryManager::_last_gc_stat is set up using the values in GCMemoryManager::_current_gc_stat. As a result the GC notification code accesses unitialized or stale data. Move the notification call after GCMemoryManager::_las_gc_stat is set, but inside the same if-block.

Summary: An assert in the management.cpp is too strong and assumes the max size is always defined on memory pools, even when we don't need to use it.
Reviewed-by: mchung, johnc

Summary: The way we were caluclating the max value meant that it might fluctuate during the run and this broke some assumptions inside the MBeans framework. This change sets the max value of each pool to -1, which means undefined according to the spec.
