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:

```
(lldb) rbbt ec
rb_control_frame_t TYPE
0x7f6fd6555fa0     EVAL   ./bootstraptest/runner.rb error!!
0x7f6fd6555f68     METHOD ./bootstraptest/runner.rb main

```

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
