I am sorry to tag all three of you as reviewers but, based on the `git blame`, you seemed to all have domain expertise in the files changed.

I am terribly aware of the fact that there are no tests in this PR -- I wasn't sure if/how/where to add them. Please let me know how I can improve the PR. 

Thank you all for all your work on LLDB!
