Include the LLDB version in the lldbassert error message, and prompt users to include it in the bug report. The majority of users that bother filing a bug report just copy past the stack trace and often forget to include this important detail. By putting it after the backtrace and before the prompt, I'm hoping it'll get copy-pasted in. rdar://146793016
