Option diff dump is added for target and optimization

	* ipa-icf.c (sem_function::equals_private): Call new functions
	cl_target_option_print_diff and cl_optimization_print_diff.
	* optc-save-gen.awk (cl_target_option_print_diff): New function.
	(cl_optimization_print_diff): Likewise.
	* opth-gen.awk: Likewise.
