RFR: 8172842 Invoke lldb with --batch from failure handler

[Staffan Larsen]

When the failure handler invokes lldb to create a core it looks something like this: 

lldb -o 'attach %p' -o 'process save-core core.%p' -o 'detach' -o 'quit' 

However if the attach command fails, the rest of the commands - including 'quit' - are not being run. This means the lldb process is hung. 

Adding '--batch' to the command line overcomes this problem. 

Thanks,
/Staffan
