	and moved here.  All callers updated.
	(count_symtabs_and_blocks): New function.
	(report_command_stats): Moved here from utils.c.  Add support for

	executed.
	(make_command_stats_cleanup): Ditto.
	(sert_per_command_cmd, show_per_command_cmd): New functions.
	(_initialize_maint_cmds): Add new commands
	mt set per-command {space,time,symtab} {on,off}.
	* maint.h: New file.

	(set_display_time, set_display_space): Moved to maint.h and renamed
	to set_per_command_time, set_per_command_space.
	* cli/cli-setshow.c (parse_cli_boolean_value): Renamed from
	parse_binary_operation and made non-static.  Don't call error,
	just return an error marker.  All callers updated.
	* cli/cli-setshow.h (parse_cli_boolean_value): Declare.
