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.

Rename miri component to miri-preview
It should fix installation via `rustup` and indicates it's not stable yet.

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.

Update and clean up several parts of CONTRIBUTING.md

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.

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...

Add provided methods `Seek::{stream_len, stream_position}`
This adds two new, provided methods to the `io::Seek` trait:
- `fn stream_len(&mut self) -> Result<u64>`
- `fn stream_position(&mut self) -> Result<u64>`
Both are added for convenience and to improve readability in user code. Reading `file.stream_len()` is much better than to manually seek two or three times. Similarly, `file.stream_position()` is much more clear than `file.seek(SeekFrom::Current(0))`.
You can find prior discussions [in this internals thread](https://internals.rust-lang.org/t/pre-rfc-idea-extend-io-seek-with-convenience-methods-with-e-g-stream-len/9262). I think I addressed all concerns in that thread.
I already wrote three RFCs to add a small new API to libstd but I noticed that many public changes to libstd happen without an RFC. So I figured I can try opening a PR directly without going through RFCs first. After all, we do have rfcbot here too. If you think this change is too big to merge without an RFC, I can still close this PR and write an RFC.

Add new test case for possible bug in BufReader
When reading a large chunk from a BufReader, if all the bytes from the buffer have been already consumed, the internal buffer is bypassed entirely. However, it is not invalidated, and it's possible to access its contents using the `seek_relative` method, because it tries to reuse the existing buffer.

Fixes for the generator transform
* Moves cleanup annotations in pretty printed MIR so that they can be tested
* Correctly determines which drops are in cleanup blocks when elaborating generator drops
* Use the correct state for poisoning a generator
Closes #58892

Rework how bootstrap tools are built
This makes bootstrap tools buildable and testable in stage 0 with the downloaded bootstrap compiler, futhermore, it makes it such that they cannot be built in any other stage.
Notably, this will also mean that compiletest may need to wait a cycle before it can use changes to `libtest`, as it no longer depends on the in-tree libtest.

Introduce assembly tests suite
The change introduces a new test suite - **Assembly** tests. The motivation behind this is an ability to perform end-to-end codegen testing with LLVM backend. Turned out, NVPTX backend sometimes missing common Rust features (`i128` and libcalls in the past, and still full atomics support) due to different reasons.
Prior to this change, basic NVPTX assembly tests were implemented within `run-make` suite. Now, it's easier to write additional and maintain existing tests for the target.
cc @gnzlbg @peterhj
cc @eddyb I adjusted mangling scheme expectation, so there is no need to change the tests for #57967

Keep last redundant linker flag, not first
When a library (L1) is passed to the linker multiple times, this is sometimes purposeful: there might be several other libraries in the linker command (L2 and L3) that all depend on L1. You'd end up with a (simplified) linker command that looks like:
```
-l2 -l1 -l3 -l1
```
With the previous behavior, when rustc encountered a redundant library, it would keep the first instance, and remove the later ones, resulting in:
```
-l2 -l1 -l3
```
This can cause a linker error, because on some platforms (e.g. Linux), the linker will only include symbols from L1 that are needed *at the point it's referenced in the command line*. So if L3 depends on additional symbols from L1, which aren't needed by L2, the linker won't know to include them, and you'll end up with "undefined symbols" errors.
A better behavior is to keep the *last* instance of the library:
```
-l2 -l3 -l1
```
This ensures that all "downstream" libraries have been included in the linker command before the "upstream" library is referenced.
Fixes rust-lang#47989

Update CI configuration for building Redox libraries

Calculate Docker cache hash precisely from Dockerfile's dependencies
#58549 changed the Docker cache calculation to include every file under `src/ci/docker`, so that when files under `dist-x86_64-linux` is changed, its dependent image `dist-i686-linux` will also be rebuilt.
However, this ultraconservative solution caused the `dist-i686-linux` to be rebuilt every time an irrelevant Dockerfile (e.g. the PowerPC ones) is changed, which increases the building time beyond 3 hours and forcing a spurious but expected failure.
This commit instead parses the Dockerfile itself and look for the actual dependencies. The scripts needs to be copied into the Docker image, which must be done with the COPY command, so we just need to find all lines with a COPY command and add the source file into the hash calculator.
Note: this script only handles single-lined COPY command in the form `COPY src1 src2 src3 dst`, since these are the only variant used inside this repository.

CI: Set job names.
This should make it easier to identify what each job is doing when looking at the Travis or Appveyor UI.
- Set `name` for each job in Travis.
- Move `CI_JOB_NAME` to the front in Appveyor so that it appears first in the UI.

Track embedded-book in the toolstate
The embedded book was tested in the tools job but the test result was never published. This PR adds maintainer information of embedded-book. This PR also requires the next update to embedded-book to pass the all tests, currently its state is test-fail.
rust-lang-nursery/rust-toolstate#10 should be merged before this PR.
