"alloc-failure" is completely unused apart from the description text in nsI- Memory.idl (and has been since before Firefox 17), while "lowering-priority" is still being checked for in the PuppetWidget, but otherwise unused as well since the feature using it was decommissioned in bug 1234176. Since we're touching the PuppetWidget code anyway, we take the opportunity to add a check for "low-memory-ongoing" instead, since similar as to how things used to be with "lowering-priority", we want to drop the LayerManager's cached resources only when receiving a real full memory-pressure event, but not for subsequent ongoing notifications.
