don't crash if we disable logging when some code already has a copy of the logger. Prior to this fix, logs were handed out as pointers and if they were held onto while a log got disabled, then it could cause a crash. Now all logs are handed out as shared pointers so this problem shouldn't happen anymore. We are also using our new shared pointers that put the shared pointer count and the object into the same allocation for a tad better performance. llvm-svn: 118319
