Add lint for 2229 migrations
Implements the first for RFC 2229 where we make the decision to migrate a root variable based on if the type of the variable needs Drop and if the root variable would be moved into the closure when the feature isn't enabled.

Update armhf-gnu to Ubuntu 20.04
This requires updating the used Linux kernel to avoid an assembler
error, the used busybox version to avoid a linker error, the used
rootfs to match the host version and the qemu flags to work with
the newer version.

- This allows us add fake information after handling migrations if
needed.
- Capture analysis also priortizes what we see earlier, which means
fake information should go in last.

Avoid building LLVM just for llvm-dwp
When the LLVM backend is disabled, the llvm-project submodule is not checked out by default. This breaks the bootstrap test for cg_clif. As cg_clif doesn't support split debuginfo anyway llvm-dwp is not necessary. Other backends would likely not want to build LLVM just for llvm-dwp either.

Rustdoc UI fixes
The first commit fixes this bug (I couldn't figure out why we were setting the width manually and it works as expected without so...):
The second commit fixes a small bug. On tablets or computer with very little width, the search section goes "over" the search input, making it impossible to click on the search input:
The third and last commit fixes two bugs that you can see in this screenshot:
The wheel is going over the search input and the search tab is going under the search results text. The bug was fixed by simply switching to "mobile mode" at a bigger width:

Implement Rust 2021 panic
This implements the Rust 2021 versions of `panic!()`. See https://github.com/rust-lang/rust/issues/80162 and https://github.com/rust-lang/rfcs/pull/3007.
It does so by replacing `{std, core}::panic!()` by a bulitin macro that expands to either `$crate::panic::panic_2015!(..)` or `$crate::panic::panic_2021!(..)` depending on the edition of the caller.
This does not yet make std's panic an alias for core's panic on Rust 2021 as the RFC proposes. That will be a separate change: https://github.com/rust-lang/rust/pull/80879/commits/c5273bdfb266c35e8eab9413aa8d58d27fdbe114 That change is blocked on figuring out what to do with https://github.com/rust-lang/rust/issues/80846 first.

Add a test for #71202
Closes #71202

Note that the test normally generates this warning:
```
warning: cannot use constants which depend on generic parameters in types

11 | | trait NotCopy {

= note: `#[warn(const_evaluatable_unchecked)]` on by default
= warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
= note: for more information, see issue #76200 <https://github.com/rust-lang/rust/issues/76200>
```
I added `allow(const_evaluatable_unchecked)`, but maybe we just don't want to add a test for this as the program is not really valid?

Remove const_in_array_repeat
Fixes #80371. Fixes #81315. Fixes #80767. Fixes #75682.
I thought there might be some issue with `Repeats(_, 0)`, but if you increase the items in the array it still ICEs. I'm not sure if this is the best fix but it does fix the given issue.

2229: Fix issues with move closures and mutability
This PR fixes two issues when feature `capture_disjoint_fields` is used.
1. Can't mutate using a mutable reference
2. Move closures try to move value out through a reference.
To do so, we
1. Compute the mutability of the capture and store it as part of the `CapturedPlace` that is written in TypeckResults
2. Restrict capture precision. Note this is temporary for now, to allow the feature to be used with move closures and ByValue captures and might change depending on discussions with the lang team.
- No Derefs are captured for ByValue captures, since that will result in value behind a reference getting moved.
- No projections are applied to raw pointers since these require unsafe blocks. We capture
them completely.

Balance sidebar `Deref` cycle check with main content
The `Deref` cycle checks added as part of #80653 were "unbalanced" in the sense
that the main content code path checks for cycles _before_ descending, while the
sidebar checks _after_. Checking _before_ is correct, so this changes the
sidebar path to match the main content path.

Clone entire `TokenCursor` when collecting tokens
Reverts PR #80830
Fixes taiki-e/pin-project#312
We can have an arbitrary number of `None`-delimited group frames pushed
on the stack due to proc-macro invocations, which can legally be exited.
Attempting to account for this would add a lot of complexity for a tiny
performance gain, so let's just use the original strategy.

Stabilize by-value `[T; N]` iterator `core::array::IntoIter`
Tracking issue: https://github.com/rust-lang/rust/issues/65798
This is unblocked now that `min_const_generics` has been stabilized in https://github.com/rust-lang/rust/pull/79135.
This PR does *not* include the corresponding `IntoIterator` impl, which is https://github.com/rust-lang/rust/pull/65819. Instead, an iterator can be constructed through the `new` method.
`new` would become unnecessary when `IntoIterator` is implemented and might be deprecated then, although it will stay stable.
