Optimize FindClass ClassNotFoundException case
With the current class loaders, there are many exceptions thrown for
each ClassNotFoundexception from FindClass calling
ClassLoader.loadClass. This CL reduces that by throwing directly from
FindClass to avoid these extra exceptions.
Numbers are from logging time taken by QuickDeliverException.
Time spent in exception throwing during startup goes down (Pixel 2 XL):
Camera: 20ms -> 5ms
Calculator: 5ms -> 2ms
Maps: 20ms -> 10ms
Added option -XX:FastClassNotFoundException=<bool> to enable or
disable the feature.
