Fix tests that incorrectly used `!@has` instead of `@!has`

The command is ``@!has`,` not `!`@has`.` I don't think these checks were
doing anything before! Ideally we would accept `!`@has`` as well, or at
least fail tests that use `!`@has`.` The current behavior seems to be
silently ignoring the check, which is very confusing.

e5a1f22f48 Initial support for Rust 2021.
Clippy treated Rust 2021 as Rust 2015, because 2018 was checked with
`==` instead of `>=`. This fixes that, such that 2018-specific things
are also enabled for 2021.

a609fb45ef Auto merge of #80547 - lqd:const_generics_defaults, r=varkor
In which we start to parse const generics defaults

As discussed in this [zulip topic](https://rust-lang.zulipchat.com/#narrow/stream/260443-project-const-generics/topic/const.20generic.20defaults), this PR extracts the parsing parts from `@JulianKnodt's` PR #75384 for a better user-experience using the newly stabilized `min_const_generics` (albeit temporary) as shown in #80507: trying to use default values on const generics currently results in parse errors, as if the user didn't use the correct syntax (which is somewhat true but also misleading).

This PR extracts (and slightly modifies in a couple places) `@JulianKnodt's` parsing code (with attribution if I've done everything correctly), AST and HIR changes, and feature gate setup.

This feature is now marked as "incomplete" and thus will also print out the expected "const generics default values are unstable" error instead of a syntax error. Note that, as I've only extracted the parsing part, the actual feature will not work at all if enabled. There will be ICEs, and inference errors on the const generics default values themselves.

Fixes #80507.

Once this merges, I'll:
- modify the const generics tracking issue to refer to the `const_generics_defaults` gate rather than the older temporary name it uses there.
- create the GH `F-const_generics_defaults` label

Add fallible Box, Arc, and Rc allocator APIs

cc https://github.com/rust-lang/rust/issues/48043

It was suggested in https://github.com/rust-lang/rust/issues/48043#issuecomment-748008486 that `Box::try_*` follows the spirit of RFC 2116. This PR is an attempt to add the relevant APIs, tied to the same feature gate. Happy to make any changes or turn this into an RFC if necessary.

60919e416d Auto merge of #6526 - matthiaskrgr:version, r=Manishearth
make clippy version number correspond to rustc version number.

clippy 0.1.50 corresponds to rustc 1.50.x

This bumps the clippy version number from 0.0.212 to 0.1.50

Fixes #6499

Notes:
I used `cargo --version` because that way we can honour the version set in the `rust-toolchain` file.
When we bump the bootstrap compiler from 1.50 to 1.51, the version numbers will have to be changed to 1.51 or the test will fail.

Add edition 2021.

🎆 Happy new ~~year~~ Rust. 🍾

This adds --edition=2021, and updates suggestions about 2018 to say "2018 *or later*".

Related Cargo PR: https://github.com/rust-lang/cargo/pull/8922

Edit: This adds the new edition as *unstable*. Without `-Z unstable-options`, `--edition=2021` results in:
```
$ rustc --edition=2021
error: edition 2021 is unstable and only available with -Z unstable-options.

Fix broken ./x.py install

During my tarball refactorings in https://github.com/rust-lang/rust/pull/79788 I changed the directory layout used by the tarball generation code, and that broke the other parts of rustbuild which hardcoded the paths of those directories. Namely, `./x.py install` relied on the uncompressed copy of the tarball left behind by `fabricate`/`rust-installer`, causing https://github.com/rust-lang/rust/issues/80494.

While the easy fix for https://github.com/rust-lang/rust/issues/80494 would've been to just update the hardcoded paths to match the new structure, that fix would leave us in the same situation if we were to change the directory layout again in the future. Instead I refactored the code to return a `GeneratedTarball` struct as the output of all the dist steps, and I put all the paths the rest of rustbuild needs to care about in its fields. That way, future changes to `src/bootstrap/tarball.rs` will not break other stuff.

Rollup merge of #80323 - camelid:codegen-base-docs, r=nagisa
Update and improve `rustc_codegen_{llvm,ssa}` docs

Fixes #75342.

These docs were very out of date and misleading. They even said that
they codegen'd the *AST*!

For some reason, the `rustc_codegen_ssa::base` docs were exactly
identical to the `rustc_codegen_llvm::base` docs. They didn't really
make sense, because they had LLVM-specific information even though
`rustc_codegen_ssa` is supposed to be somewhat generic. So I removed
them as they were misleading.

r? ``@pnkfelix`` maybe?
