0491a23177 Auto merge of #37192 - cristicbz:rust-rc-into-raw, r=brson
Add `{into,from}_raw` to Rc and Arc

These methods convert to and from a `*const T` for `Rc` and `Arc` similar to the way they work on `Box`. The only slight complication is that `from_raw` needs to offset the pointer back to find the beginning of the `RcBox`/`ArcInner`.

I felt this is a fairly small addition, filling in a gap (when compared to `Box`) so it wouldn't need an RFC. The motivation is primarily for FFI.

(I'll create an issue and update a PR with the issue number if reviewers agree with the change in principle **Edit: done #37197**)

~~Edit: This was initially `{into,from}_raw` but concerns were raised about the possible footgun if mixed with the methods of the same name of `Box`.~~

Edit: This was went from `{into,from}_raw` to `{into,from}_inner_raw` then back to `{into,from}_raw` during review.

31a8638e5e rustbuild: Tweak for vendored dependencies
A few changes are included here:

* The `winapi` and `url` dependencies were dropped. The source code for these
  projects is pretty weighty, and we're about to vendor them, so let's not
  commit to that intake just yet. If necessary we can vendor them later but for
  now it shouldn't be necessary.

* The `--frozen` flag is now always passed to Cargo, obviating the need for
  tidy's `cargo_lock` check.

* Tidy was updated to not check the vendor directory

Closes #34687

31a508e118 Allow proc_macro functions to whitelist specific attributes
By using a second attribute `attributes(Bar)` on
proc_macro_derive, whitelist any attributes with
the name `Bar` in the deriving item. This allows
a proc_macro function to use custom attribtues
without a custom attribute error or unused attribute
lint.

Stabilize `..` in tuple (struct) patterns

I'd like to nominate `..` in tuple and tuple struct patterns for stabilization.
This feature is a relatively small extension to existing stable functionality and doesn't have known blockers.
The feature first appeared in Rust 1.10 6 months ago.
An example of use: https://github.com/rust-lang/rust/pull/36203

rustbuild: support MIPS host builds

There is a *little* code duplication, but primarily for sake of "match exhaustiveness". Let's blame Linux/MIPS for not exposing endianness explicitly in `uname -m` (that's user-space interface and as such is frozen).

Currently the build won't work as we have to wait for a new stage0 for the MIPS host compilers, but this paves the way to self-hosted Rust on MIPS. The cross-compiled MIPS binaries are confirmed to work on the Loongson 3A2000 (MIPS64r2-compatible) so we have plenty of confidence that they'll work on other MIPS platforms too, as Linux/MIPS user-space ABI is consistent across machines of the same bitness.

045a727b83 Auto merge of #37605 - dsprenkels:arc-max-refcount, r=alexcrichton
Fix Arc::clone()'s MAX_REFCOUNT check (off-by-one)

Before, the strong count of an `Arc` could be set to
`MAX_REFCOUNT + 1`, because when this happened, `old_size` would
be exactly `MAX_REFCOUNT`. `Arc::clone()` would not abort.

This commit changes the check in `Arc::clone()` to also abort if
the old value is equal to `MAX_REFCOUNT`, because then the new
value will be equal to `MAX_REFCOUNT + 1`.

A test would require allocating memory for `isize::MAX` pointers.
This would probably crash any machine, so no test is submitted
with this commit.

a28c01bdf9 Remove mention of mipsel target_arch
The `mipsel` `target_arch` was introduced with the initial MIPSel
support (rust-lang/rust@82ec1aef29),
but was subsequently removed with implementation of the Flexible Target
Specification (Rust RFC 0131,
rust-lang/rust@3a8f4ec32a).
This is the only remaining instance in rustc. All others are in the libc
repo, and are fixed in rust-lang/libc@b3676593f6.

macros: improve shadowing checks

This PR improves macro-expanded shadowing checks to work with out-of-(pre)order expansion.

Out-of-order expansion became possible in #37084, so this technically a [breaking-change] for nightly.
The regression test from this PR is an example of code that would break.

99aaccd32f Add a comment to Arc::MAX_REFCOUNT
The constant name `MAX_REFCOUNT` suggests that the value is a
_hard_ limit on the amount of references to an `Arc`. This is
a more soft limit however. This commit adds a comment to the
constant to annotate this.

[4/n] rustc: harden against InferOk having obligations in more cases.

_This is part of a series ([prev](https://github.com/rust-lang/rust/pull/37402) | [next](https://github.com/rust-lang/rust/pull/37408)) of patches designed to rework rustc into an out-of-order on-demand pipeline model for both better feature support (e.g. [MIR-based](https://github.com/solson/miri) early constant evaluation) and incremental execution of compiler passes (e.g. type-checking), with beneficial consequences to IDE support as well.
If any motivation is unclear, please ask for additional PR description clarifications or code comments._

<hr>

This adds more asserts that `InferOk` results have no obligations, pending completion of #32730.

Each of these could accidentally drop obligations on the floor if they start getting produced by unification, and a future change does just that, in order to produce a "shallow success" (hopefully leading to ambiguities during trait selection), _without_ the possibility of an eventual success - mostly guarded by ICEs for now.

Add example using Self to reference

When I first came across `Self` I had a hard time finding references to it in the docs (and it's also been asked about on [StackOverflow](http://stackoverflow.com/questions/32304595/whats-the-difference-between-self-and-self).

I hope this example provides someone who comes across it for the first time a little more help.  If there is a better way to show an example actually using `Self`, I'm happy to modify this.  It was just the simplest place to start I could see.
