Mostly recover a Ruby stack trace from a core file
Update the lldb script so it can mostly recover a Ruby stack trace from
a core file. It's still missing line numbers and dealing with CFUNCs,
but you use it like this:
```

Getting the main execution context is difficult (it is stored in a
thread local) so for now you must supply an ec and this will make a
backtrace
