dbgcnt: print list after compilation

gcc/ChangeLog:

	* common.opt: Remove -fdbg-cnt-list from deferred options.
	* dbgcnt.c (dbg_cnt_set_limit_by_index): Make a copy
	to original_limits.
	(dbg_cnt_list_all_counters): Print also current counter value
	and print to stderr.
	* opts-global.c (handle_common_deferred_options): Do not handle
	-fdbg-cnt-list.
	* opts.c (common_handle_option): Likewise.
	* toplev.c (finalize): Handle it after compilation here.
