This allows incremental modes to generate error messages that are
both better and more consistent with non-incremental modes.

Storing the data in a parallel array is kind of ugly and was done for
consistency with dep_prios. It might be worth doing a refactor, though
any other way will make the json bigger, which is presumbably why
dep_prios was done with an array.

This is a big yak-shave: this import line number thing was the root cause of differing error message behavior when using fine-grained cache info.
