Unified: Include source skeletons in corpus output

Regenerates all of the existing corpus output files to include source
skeletons. Note that this already reveals some issues with our current
locations:

- arguments with trailing commas have a location that includes said
comma,
- switch_case nodes contain a `block` that encompasses the `case`
statement itself.

These will be fixed in due course.
