Breaking on a particular caller (lldb->General)

Say that we have a borkFunction, and it's called by greebleFunction and hooverFunction:

    greebleFunction ();
    hooverFunction ();

And say that we want to break when borkFunction is called by hoover, and not by greeble.

(lldb) breakpoint set -n borkFunction
Breakpoint created: 1: name = 'borkFunction', locations = 1

(lldb) breakpoint command add --script-type python 1
Enter your Python command(s). Type 'DONE' to end.
> thread = frame.GetThread()
> caller = thread.GetFrameAtIndex(1)
> if caller.GetFunctionName() != "hooverFunction":
>     process = thread.GetProcess()
>     process.Continue()
> DONE

(lldb) run
greeble!
    bork!
hoover!
