Some fixes to the reorganize_definitions transform for c2rust-refactor to make it work again.

Several questions inline; everything else looks good.

What do we need this for? Especially if it's not used, I'd rather not add to expect! given that assert_matches! does the same and is much more standardized.

expect! is used in a ton of places in the project, it would be nice to get rid of it but that's a separate side project. While it's in use, I thought it would be useful for it to output better error messages (and I needed that during development).
