Enable check-cfg in stage0
Now that the bootstrap cargo supports `rustc-check-cfg` we can now enable it with `-Zcheck-cfg=output` and use it in `rustc_llvm` to unblock `--check-cfg` support in stage0.

- docs: fixing minor error in the default timing report filename (rust-lang/cargo#10879)
- Stabilize `--crate-type` flag for `cargo rustc` (rust-lang/cargo#10838)
- Stabilize `-Zmultitarget` (rust-lang/cargo#10766)
- Clean up leftover in unstable documentation (rust-lang/cargo#10874)
- Normalize path for `cargo vendor` output (rust-lang/cargo#10668)
- add a reason to `masquerade_as_nightly_cargo` so it is searchable (rust-lang/cargo#10868)
- Allow '.' in workspace.default-members in non-virtual workspaces. (rust-lang/cargo#10784)
- remove`.masquerade_as_nightly_cargo()` from various tests the no longer need it (rust-lang/cargo#10867)
- remove `.masquerade_as_nightly_cargo()` from build_script_extra_link_arg.rs (rust-lang/cargo#10866)
It looks like the last time had left some remaining cfg's -- which made me think
that the stage0 bump was actually successful. This brings us to a released 1.62
beta though.
fix: Prevent panic in Remove Unused Parameter assist
Instead of calling `builder.delete` for every text range we find with
`process_usage`, we now ensure that the ranges do not overlap before removing
them. If a range is fully contained by a prior one, it is dropped.
fixes#12784
Let's avoid using two different terms for the same thing -- let's just call it "provenance" everywhere.
In Miri, provenance consists of an AllocId and an SbTag (Stacked Borrows tag), which made this even more confusing.
Improve the function pointer docs
This is #97842 but for function pointers instead of tuples. The concept is basically the same.
* Reduce duplicate impls; show `fn (T₁, T₂, …, Tₙ)` and include a sentence saying that there exists up to twelve of them.
* Show `Copy` and `Clone`.
* Show auto traits like `Send` and `Sync`, and blanket impls like `Any`.

interpret: make some large types not Copy
Also remove some unused trait impls (mostly HashStable).
This didn't find any unnecessary copies that I managed to avoid, but it might still be better to require explicit clone for these types? Not sure.

use `par_for_each_in` in `par_body_owners` and `collect_crate_mono_items`
Using `par_iter` in non-parallel mode will cause the entire process to abort when any iteration panics. So we can use `par_for_each_in` instead to make the error message consistent with parallel mode. This means that the compiler will output more error messages in some cases. This fixes the following ui tests when set `parallel-compiler = true`:
```
[ui] src/test\ui\privacy\privacy2.rs
[ui] src/test\ui\privacy\privacy3.rs
[ui] src/test\ui\type_length_limit.rs
```
This refers to #68171
Updates #75760
Revert "Stabilize $$ in Rust 1.63.0"
This mechanically reverts commit 9edaa76adc, the one commit from #95860.
https://github.com/rust-lang/rust/issues/99035; the behavior of `$$crate` is potentially unexpected and not ready to be stabilized. https://github.com/rust-lang/rust/pull/99193 attempts to forbid `$$crate` without also destabilizing `$$` more generally.
`@rustbot` modify labels +T-compiler +T-lang +P-medium +beta-nominated +relnotes
(applying the labels I think are accurate from the issue and alternative partial revert)

use body's param-env when checking if type needs drop
The type comes from the body, so we should be using the body's param-env, as opposed to the ADT's param env, because we know less in the latter compared to the former.
Fixes#99375
Add E0790 as more specific variant of E0283
Fixes#81701
I think this should be good to go, there are only two things where I am somewhat unsure:
- Is there a better way to get the fully-qualified path for the suggestion? I tried `self.tcx.def_path_str`, but that didn't seem to always give a correct path for the context.
- Should all this be extracted into it's own method or is it fine where it is?

core::any: replace some generic types with impl Trait
This gives a cleaner API since the caller only specifies the concrete type they usually want to.

Upgrade to expect-test@1.4.0, add CARGO_WORKSPACE_DIR env var
This should make ra's test suite runnable from within `rust-analyzer/rust`.
`@cuviper` ran into that when trying to run RA tests from rust CI: https://github.com/rust-lang/rust/pull/99444#issuecomment-1188844202
Fix `Skip::next` for non-fused inner iterators
`iter.skip(n).next()` will currently call `nth` and `next` in succession on `iter`, without checking whether `nth` exhausts the iterator. Using `?` to propagate a `None` value returned by `nth` avoids this.
Update invalid atomic ordering lint
The restriction that success ordering must be at least as strong as its
failure ordering in compare-exchange operations was lifted in #98383.
Use span_bug for unexpected field projection type
Improves the compiler error backtrace information, as shown in #99363,
by using `span_bug` instead of `bug`.
New output:
