Well done! I am glad to see this works well for Linux.
One question: are all of the signals you added actually signals? It looked like it from what I can tell. One of the hacks we did in GDB for mach exceptions was to make up new fake signal numbers because the debugger wanted to deal with signals.
One thing I just want to make sure happens in LLDB is that we never have to make up anything. For mach exceptions, we have a StopInfo subclass that is not part of the built in StopInfo stuff: StopInfoMachException. This class takes care of doing all of the special mach things that no other platform really cares about.
So if there are things that aren't signals in your recent checkin, you might consider making a StopInfoLinux to take care of any special things that aren't signal related.
