fixes omission in refactoring for record, inner to outer and pullup.

[homberghp]

This PR closes #7044

The issue describes that record info was lost when doing and inner to outer or pull up refactoring.

In this pull request

• tests to show the issue.
• junit test helper to make test output better understandable: AssertLinesEqualHelpers.java
• added factory for Record classTree in TreeFactory and TreeMaker
• improved methods in CasualDiff and VeryPretty to pick op parameters from record in constructor, so that
  var args are preserved.

And also: minimal drive-by changes.

Sorry for the inconvenience, if I messed up. According to lahodaj and mbien my earlier attempts were way too big, to which I agree. Rolling back my rejected changes was undoable, so I simply started again and picked the usable parts
of the earlier attempt.

Is this PR reviewable at this point?

Yes, its is reviewable and way smaller.

It passes all tests, including some I had to add after I found some additional issues, where previous attempts messed
up unrelated tests, in particular Rename.
In this version I stick to the bare minimum to in the code, although some more work has been done on the testing front.

CasualDiff and its friends put up a fair fight to understand them.

It was a steep learning curve for me. Thank you for your patience.

@mbien @lahodaj Ready for review.
I merged the PRs into one and applied all corrections you both suggested in your reviews of my earlier PRs.

Thank you both for your patience and teaching.
Have a nice day
