Rustup
Done with
```bash
git subtree push -P src/tools/clippy git@github.com:flip1995/rust-clippy rustup
```
from https://github.com/flip1995/rust/tree/clippyup
A rebase was required to get rid of empty merge commits, that somehow were not empty? 🤔

Allow `use super::*;` glob imports
changelog: Allow super::* glob imports
fixes#5554fixes#5569
A first pass at #5554 - this allows all `use super::*` to pass, which may or may not be desirable. The original issue was around allowing test modules to import their entire parent modules - I'm happy to modify this to do that instead, may just need some guidance on how to implement that (I played around a bit with #[cfg(test)] but from what I can gather, clippy itself isn't in test mode when running, even if the code in question is being checked for the test target).
Extend example for the `unneeded_field_pattern` lint
Current example is incorrect (or pseudo-code) because a struct name is omitted. I have used the code from the tests instead. Perhaps this example can be made less verbose, but I think it is more convenient to see a "real" code as an example.

Update to rustc changes
changelog: none
So, turns out `git subtree push` dies in various interesting ways, but the source cause is that the rustc repo looks like
```
--- A --- B --- C ---
\--- D ---/
```
where `B` is the commit where I added clippy to rustc and `D` is an arbitrary other PR and `C` is the master branch (or an earlier commit in it). When we now do `git subtree push`, it doesn't stop looking for things to merge at `B` as it needs to look at `D`, too, but then the bad thing happens, and it doesn't stop at `A` either, and just goes on looking at the entire history of rustc in a recursive bash script. That recursion then quickly runs into a stack overflow. While we can increase the stack size via `ulimit -s 60000`, that just means I was waiting for 30 minutes looking at `git subtree push` counting up the number of commits it has looked at. I aborted that, as a process that needs 30 mins for a push is not reasonable.
This PR cheats by just doing a `cp -r ../rustc/src/tools/clippy/* .` inside my clippy checkout and committing all changes. I'm working on getting us a better workflow, but until then, this workaround will work nicely. Note that this requires a `git subrepo pull` to have occurred in the `rustc` checkout. It's not necessary to merge that pull in order to update clippy, it's just necessary in order to not revert code in the clippy repo that hasn't been synced yet to the rustc repo.
Fix match on vec items: match on vec[..]
