i386.c (ix86_option_override_internal): For stack_protector_guard related options...

	* config/i386/i386.c (ix86_option_override_internal): For
	stack_protector_guard related options, use opts_set->x_ instead
	of global_options_set. and prefix options with opts->x_ .  Move
	defaults for offset and reg into else block.
