Use the object crate for metadata reading
This allows sharing the metadata reader between cg_llvm, cg_clif and other codegen backends.
This is not currently useful for rlib reading with cg_spirv ([rust-gpu](https://github.com/EmbarkStudios/rust-gpu/)) as it uses tar rather than ar as .rlib format, but it is useful for dylib reading required for loading proc macros. (cc `@eddyb)`
The object crate is already trusted as dependency of libstd through backtrace. As far as I know it supports reading all object file formats used by targets for which we support rust dylibs with crate metadata, but I am not certain. If this happens to not be the case, I could keep using LLVM for reading dylib metadata.
Marked as WIP for a perf run and as it is based on #83637.
Implement `x.py test src/tools/clippy --bless`
- Add clippy_dev to the rust workspace
Before, it would give an error that it wasn't either included or
excluded from the workspace:
```
error: current package believes it's in a workspace when it's not:
current: /home/joshua/rustc/src/tools/clippy/clippy_dev/Cargo.toml
workspace: /home/joshua/rustc/Cargo.toml
this may be fixable by adding `src/tools/clippy/clippy_dev` to the `workspace.members` array of the manifest located at: /home/joshua/rustc/Cargo.toml
Alternatively, to keep it out of the workspace, add the package to the `workspace.exclude` array, or add an empty `[workspace]` table to the package's manifest.
```
- Change clippy's copy of compiletest not to special-case
rust-lang/rust. Using OUT_DIR confused `clippy_dev` and it couldn't find
the test outputs. This is one of the reasons why `cargo dev bless` used
to silently do nothing (the others were that `CARGO_TARGET_DIR` and
`PROFILE` weren't set appropriately).
- Run clippy_dev on test failure
I tested this by removing a couple lines from a stderr file, and they
were correctly replaced.
- Fix clippy_dev warnings
Update grab bag
This PR slides a bunch of crate versions forward until suddenly a bunch of deps fall out of the tree!
In doing so this mostly picks up a version bump in the `redox_users` crate which makes most of the features default to optional.
crossbeam-utils 0.7 => 0.8.3 (where applicable)
https://github.com/crossbeam-rs/crossbeam/blob/master/crossbeam-utils/CHANGELOG.md
directories 3.0.1 => 3.0.2
ignore 0.4.16 => 0.4.17
tempfile 3.0.5 => tempfile 3.2
Removes constant_time_eq from deps exceptions
Removes arrayref from deps exceptions
And also removes:
- blake2b_simd
- const_fn (the package, not the feature)
- constant_time_eq
- redox_users 0.3.4
- rust-argon2

Use arrayvec 0.7, drop smallvec 0.6
With the arrival of min const generics, many alt-vec libraries have
updated to use it in some way and arrayvec is no exception. Use the
latest with minor refactoring.
Also, rustc_workspace_hack is the only user of smallvec 0.6 in the
entire tree, so drop it.

Update stdarch submodule (to before it switched to const generics)
https://github.com/rust-lang/rust/pull/83278#issuecomment-812389823: This unblocks #82539.
Major changes:
- More AVX-512 intrinsics.
- More ARM & AArch64 NEON intrinsics.
- Updated unstable WASM intrinsics to latest draft standards.
- std_detect is now a separate crate instead of a submodule of std.
I double-checked and the first use of const generics looks like 8d5017861e, which isn't included in this PR.
r? `@Amanieu`
This also includes a cherry-pick of
ec1461905b
and https://github.com/rust-lang/stdarch/pull/1108 to fix a build
failure.
It also adds a re-export of various macros to the crate root of libstd -
previously they would show up automatically because std_detect was defined
in the same crate.
Bump libc dependency of std to 0.2.93
Update `libc` dependency of `std` to the latest version. That allows to consume the https://github.com/rust-lang/libc/pull/2131 fix and fix build for the `mipsel-unknown-linux-uclibc` target.
r? `@JohnTitor`
Add an Mmap wrapper to rustc_data_structures
This wrapper implements StableAddress and falls back to directly reading the file on wasm32.
Taken from #83640, which I will close due to the perf regression.
Remove/replace some outdated crates from the dependency tree
- Remove `cloudabi` by updating `parking_lot` to 0.11.1.
- Replace `packed_simd` with `packed_simd2` by updating `bytecount` to 0.6.2.
