Summary:
Right now our argument completions are rather cryptic for command options as they only list the letters:
```
(lldb) breakpoint set -
Available completions:
-G
-C
-c
-d
-i
-o
-q
-t
-x
[...]
```
With the new completion API we can easily extend this with the flag description so that it looks like this now:
```
(lldb) breakpoint set -
Available completions:
-G -- The breakpoint will auto-continue after running its commands.
-C -- A command to run when the breakpoint is hit, can be provided more than once, the commands will get run in order left to right.
-c -- The breakpoint stops only if this condition expression evaluates to true.
-d -- Disable the breakpoint.
-i -- Set the number of times this breakpoint is skipped before stopping.
-o -- The breakpoint is deleted the first time it stop causes a stop.
-q -- The breakpoint stops only for threads in the queue whose name is given by this argument.
-t -- The breakpoint stops only for the thread whose TID matches this argument.
-x -- The breakpoint stops only for the thread whose index matches this argument.
```
The same happens with --long-options now.
