Use `yarn` instead of `npm` for JS/TS dependencies Building on `@lolbinarycat` 's excellent work ( rust-lang/rust#148672 ). `npm` apparently has certain edge-cases where it doesn't actually respect the lockfile it's fed, which has led to at least one [CI breakage](https://rust-lang.zulipchat.com/#narrow/channel/242791-t-infra/topic/CI.20keeps.20failing.20because.20of.20npm.20error/near/554420543). `yarn` seems to not suffer from those same issues, and also has a `--frozen` flag for its `install` command
miri subtree update Contains the fix for rust-lang/miri#4698, which we should get shipped ASAP. Subtree update of `miri` to rust-lang/miri@0fea24a. Created using https://github.com/rust-lang/josh-sync. r? `@ghost`
stdarch subtree update Subtree update of `stdarch` to rust-lang/stdarch@50134e1. Created using https://github.com/rust-lang/josh-sync. The only interesting commit is the final one, which enables the `avx10_target_feature` feature in the standard library, because it is now used in `stdarch`. r? `@sayantn` (or whoever, this is just a straightforward sync)
Add doc for va_list APIs I observed that [PR146521](rust-lang/rust#146521) submitted two weeks ago resolved some documentation issues related to `VaListImpl`, similar to the previous [PR136969](rust-lang/rust#136969). This PR specifically adds requirements about argument availability for `VaListImpl::arg`, and also adds safety descriptions to the three associated intrinsic APIs.
alloc: fix `Debug` implementation of `ExtractIf` I noticed this while reviewing rust-lang/rust#141032. Calling `get` on the inner `Vec` never returns `Some` as the `Vec`'s length is temporarily set to zero while the `ExtractIf` exists.

rustc_public: Make Id types !Send / !Sync These types are Id's to a table stored in TLS, so using them from another tread will either panic, or give wrong results. Therefor, I've added a ~~`ReferencesTls`~~`ThreadLocalIndex` marker type, which ensures types arn't `Send`/`Sync`. This is a breaking change for users of the `rustc_public` crate. ~~It also changes how `DefId` and similar are `Serialize`d. It would be possible to preserve the old behavior if that's needed, but I couldn't see any tests for these.~~ EDIT: Not anymore: rust-lang/rust#148261 (comment) Zulip Discussion: https://rust-lang.zulipchat.com/#narrow/channel/320896-project-stable-mir/topic/WDYM.20.22should.20not.20.20be.20shared.20across.20threads.22/with/547374171

See if this is the time we can remove `layout::size_align` This was a bad idea before, but now that `size_of` and `align_of` work completely differently than when removing it was first tried in 2020, maybe it makes sense now. (Or maybe I'll just add another attempt to the list in the comments...) r? ghost
Bump compiler dependencies rust-lang/rust#145849 (comment) This manually downgrades the `wasip`/`wit-bindgen`/`getrandom` deps to avoid pulling in a binary blob, but it would be good to pin this automatically in a way which doesn't cause these blobs to be pulled in.

…li-obk Skip unused variables warning for unreachable code Fixes rust-lang/rust#148373 These warnings are not reported on stable branch, but are now reported on the beta. I tried another solution to record whether a `local` is reachable in `find_dead_assignments`, but the code in this PR seems simpler. r? `@cjgillot`

Turn moves into copies after copy propagation Previously copy propagation presumed that there is further unspecified distinction between move operands and copy operands in assignments and propagated moves from assignments into terminators. This is inconsistent with current operational semantics. Turn moves into copies after copy propagation to preserve existing behavior. Fixes rust-lang/rust#137936. Fixes rust-lang/rust#146423. r? `@cjgillot`
Fix MaybeUninit codegen using GVN This is an alternative to rust-lang/rust#142837, based on rust-lang/rust#146355 (comment). The general approach I took here is to aggressively propagate anything that is entirely uninitialized. GVN generally takes the approach of only synthesizing small types, but we need to generate large consts to fix the codegen issue. I also added a special case to MIR dumps for this where now an entirely uninit const is printed as `const <uninit>`, because otherwise we end up with extremely verbose dumps of the new consts. After GVN though, we still end up with a lot of MIR that looks like this: ``` StorageLive(_1); _1 = const <uninit>; _2 = &raw mut _1; ``` Which will break tests/codegen-llvm/maybeuninit-rvo.rs with the naive lowering. I think the ideal fix here is to somehow omit these `_1 = const <uninit>` assignments that come directly after a StorageLive, but I'm not sure how to do that. For now at least, ignoring such assignments (even if they don't come right after a StorageLive) in codegen seems to work. Note that since GVN is based on synthesizing a `ConstValue` which has a defined layout, this scenario still gets deoptimized by LLVM. ```rust #![feature(rustc_attrs)] #![crate_type = "lib"] use std::mem::MaybeUninit; #[unsafe(no_mangle)] pub fn oof() -> [[MaybeUninit<u8>; 8]; 8] { #[rustc_no_mir_inline] pub fn inner<T: Copy>() -> [[MaybeUninit<T>; 8]; 8] { [[MaybeUninit::uninit(); 8]; 8] } inner() } ``` This case can be handled correctly if enough inlining has happened, or it could be handled by post-mono GVN. Synthesizing `UnevaluatedConst` or some other special kind of const seems dubious.
Simplify `jemalloc` setup (without perf regression) Reland rust-lang/rust#146627 after fixing [the performance regression](rust-lang/rust#148851 (comment)) that caused it to be reverted in rust-lang/rust#148896. This avoids 65f0b7a (second commit in the initial PR), and adds a comment explaining why `extern crate` is needed here instead of `use` (we need to load `tikv_jemalloc_sys` from the sysroot because of rust-lang/cc-rs#1613). r? Kobzol
