Use references to Objective C classes instead of looking classes up by name.

Browse Source 
This should reduce binary size slightly, small performance improvement, and improve linkage by forcing references to all used classes.

Note that this maintains backwards compatibility for sources generated by older protoc for the time being. If you want the benefits
you will need to recompile your protos with the newer protoc.
