The root of the problem is that a string literal pattern is essentially of the form `&LITERAL`, in a single block, while match checking wants to split that. To fix that, I added a type field to the patterns in match checking, which allows us to distinguish between a full and split pattern. That file is ugly and needs to be cleaned. However, `trans::_match` calls it, so I think we should delay the cleanup until we kill that. Fixes #30240
