Add user data to spans.
Add line numbers to laid out fragments.
Update formatting in golden files.

All golden files are regenerated to use the new formatting.

This only affects whitespace (including newlines), otherwise the golden
values are perfectly equal. You can check this using the command:
`git show --word-diff-regex='[^[:space:]]'`
Rename golden files for easier tracking.
