Updated patch

As jistone suggested, keep the variables/arguments as set<string>
of "name:type" and make set-intersection before printing.

$ ./stap -L signal.send
signal.send name:string pid_name:string send2queue:long shared:long
si_code:string sig:long sig_name:string sig_pid:long sinfo:long task:long
$group:int $sig:int $t:struct task_struct*

Now, only those items existing in all branch will be printed.
