It might be nice to have a helper function that checks to make sure there is an error string on error cases and if there is no error string when error.Success() is false or error.Fail() is true, then set the error string to "unknown error".

Actually, are we using m_lldbResult now? I didn't realize its type was lldb::SBCommandReturnObject. That was only needed if we were calling:
```
rSessionInfo.GetDebugger().GetCommandInterpreter().HandleCommand(pCmd, m_lldbResult);
```

So we can get rid of all "lldb::SBCommandReturnObject m_lldbResult" member variables in any lldb-mi functions where we switch to using the API.
