bootstrapping with -O3.  Also bootstrapped/regtested with -O2
and committed as obvious.

	* c-common.c (handle_nonnull_attribute, check_function_nonnull):
	Initialize arg_num.
	* c-format.c (handle_format_attribute): Initialize format_num.
	* rtlanal.c (get_related_value): Initialize get_jump_table_offset
