Auto merge of #43709 - zackmdavis:de-orphan_extended_information, r=GuillaumeGomez

de-orphan extended information

Bizarrely, librustc_passes, librustc_plugin, librustc_mir, and libsyntax [weren't getting their error explanations registered](https://github.com/rust-lang/rust/issues/35284) (leaving _several_ error codes absent from [the index](https://doc.rust-lang.org/nightly/error-index.html) and `--explain`). This surfaced a few latent doctest failures that were fixed where readily possible and ignored (with a recorded excuse) if not.

Also, we don't issue E0563 anymore.

 An inclusive range needs an end in order to *include* it. If you just need a
 start and no end, use a non-inclusive range (with `..`):
 
 ```
-let tmp = vec![0, 1, 2, 3, 4, 4, 3, 3, 2, 1];
-let x = &tmp[1..]; // ok!
+fn main() {
+    let tmp = vec![0, 1, 2, 3, 4, 4, 3, 3, 2, 1];
+    let x = &tmp[1..]; // ok!
+}
 ```
 
 Or put an end to your inclusive range:
 
 ```
-let tmp = vec![0, 1, 2, 3, 4, 4, 3, 3, 2, 1];
-let x = &tmp[1...3]; // ok!
