When encountering code like the following, suggest borrowing the for loop
head to avoid moving it into the for loop pattern:
```
fn main() {
let a = vec![1, 2, 3];
for i in &a {
for j in a {
println!("{} * {} = {}", i, j, i * j);
}
}
}
```
(WIP) Small fixes in chalkification
Small fixes around region constraints and builtin impls. There are still some type inference errors, for example the following code errors out:
```rust
fn main() {
let mut x: Vec<i32> = Vec::new();
// ^^^^^^^^ cannot infer type for `std::vec::Vec<_>`
}
```
but explicitly specifying `Vec::<i32>::new` works.
With these few fixes, the following code now passes type-checking:
```rust
fn main() {
let mut x: Vec<i32> = Vec::<i32>::new();
x.push(5);
println!("{:?}", x);
}
```
I also fixed the implied bounds bug as discussed on Zulip and in https://github.com/rust-lang-nursery/chalk/pull/206

Remove `track_errors` from `check_match`, `typeck_item_bodies` and `register_plugins`
In the spirit of continuing through errors in type checking (#39275), remove `track_errors` from a couple of locations in the codebase.
HirIdification: kill off NodeId stragglers
The final stages of HirIdification (#57578).
This PR, along with https://github.com/rust-lang/rust/pull/59042, should finalize the HirIdification process (at least the more straightforward bits).
- replace `NodeId` with `HirId` in `trait_impls`
- remove all `NodeId`s from `borrowck`
- remove all `NodeId`s from `typeck`
- remove all `NodeId`s from `mir`
- remove `trait_auto_impl` (unused)
I would be cool to also remove `NodeId` from `hir::def::Def`, `middle::privacy::AccessLevel` and `hir::ItemId`, but I don't know if this is feasible.
I'll be happy to do more if I've missed anything.
middle: replace NodeId with HirId in AccessLevels
Pushing the limits of HirIdification (#57578).
Replaces `NodeId` with `HirId` in `middle::privacy::AccessLevels`. Actually this time I was more successful and cracked it; I probably tried to HirIdify too much at once when I attempted it last time ^^.

cleanup: Remove compile-fail-fulldeps directory again
It was already removed once in https://github.com/rust-lang/rust/pull/56444, but was partially resurrected by rebase of some other PR.
Move some bench tests back from libtest
It doesn't make much sense to test these on rust-lang/libtest since they exercise the `#[bench]` macro which is part of rust-lang/rust.
This PR moves these tests back here.

Do not complain about non-existing fields after parse recovery
When failing to parse struct-like enum variants, the ADT gets recorded
as having no fields. Record that we have actually recovered during
parsing of this variant to avoid complaing about non-existing fields
when actually using it.
Fix#57361.
consistent naming for Rhs type parameter in libcore/ops
Rename RHS type parameter occurrences RHS->Rhs to make it consistent throughout files and follow naming conventions.
Add const generics to rustdoc
Split out from #53645. This work is a collaborative effort with @yodaldevoid.
The `FIXME`s are waiting on a refactor to `LazyConst`. I'll address these in a follow up, but I thought it would be better to implement the rest now to avoid bitrot.
r? @QuietMisdreavus
Add peer_addr function to UdpSocket
Fixes#59104
This is my first pull request to Rust, so opening early for some feedback.
My biggest question is: where do I add tests?
Any comments very much appreciated!
Refactor tools/build-mainfest
I saw some duplication in https://github.com/rust-lang/rust/pull/58990 and got an itch... Will likely need to be rebased when that lands. Hopefully the PR should have zero semantic changes...
