Any arguments that are not options to the "lldb" command line driver, now get 

used as the arguments for the inferior program. So for example you can do

% lldb /bin/ls /tmp ~/Documents

And "lldb" will use "/bin/ls" as the program and send arguments "/tmp" and
"~/Documents" as the launch args.

If you specify a file, then all remaining args after option parsing
will be used for program arguments:

% lldb -f /bin/ls /tmp ~/Documents

If you need to pass option values to your inferior program, just terminate
the "lldb" command line driver options with "--":

% lldb -- /bin/ls -AFl /tmp

The arguments are placed into the "settings" variable named 
"target.process.run-args". This allows you to just run the program using
"process launch" and, if no args are specified on that command, the 
"target.process.run-args" values will be used:

% lldb -- /bin/ls -AFl /tmp
Current executable set to '/bin/ls' (x86_64).
(lldb) settings show target.process.run-args 
target.process.run-args (array):
  [0]: '-AFl'
  [1]: '/tmp'
(lldb) 
(lldb) r
Process 56753 launched: '/bin/ls' (x86_64)
