[Bug uprobes/6901] New: process.syscall $arg[0] syntax

[mhiramat at redhat dot com]

Because all kind of syscall are probed by process.syscall handler, we can't know
statically how many argument which we can access in process.syscall.
However, we can provide a static table which has pairs of syscall number and the
number of arguments, like __syscall_argc[]. In that case, $arg[] array is
useful, because we can trace only valid arguments as $arg[0] ...
$arg[__syscall_argc[$syscall]].
