LGTM. Let's land this once the CI is green (and after checking whether we can split the `datasizeof` change out).

Once you land this, please coordinate with LLDB for the data formatters change. Thanks for pushing this through, this is an amazing improvement that required some of the most advanced technical skills I've seen. This is impressive.
