`rustc_middle` and `rustc_query_system` both have a file called `dep_node.rs` with a big comment at the top, and the comments are very similar. The one in `rustc_query_system` looks like the original, and the one in `rustc_middle` is a copy with some improvements. This commit removes the comment from `rustc_middle` and updates the one in `rustc_query_system` to include the improvements. I did it this way because `rustc_query_system` is the crate that defines `DepNode`, and so seems like the right place for the comment.
The same comments are on the `DepNodeExt` trait and the single impl of that trait, immediately below. This commit eliminates the duplication.
It has a single call site and removing it makes the code simpler. Perhaps there were more uses at some point in the past?
The `field_name`/`field_ty` don't need to be parameters, they can be hardcoded.
- Mention THIR. - Removed mentions of non-existent READMEs.
I *think* this addresses what the `FIXME` comments are asking for.
