PR libobjc/18764
* class.c (__objc_add_class_to_hash): Return YES if the class was
added, and NO if it already existed.
* init.c (__objc_init_class): If __objc_add_class_to_hash returns
NO, then abort the program with an error message.
* objc-private/runtime.h (__objc_add_class_to_hash): Updated
declaration.
