- 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.

Sync rustc_codegen_cranelift
The highlight of this sync are abi compatibility with cg_llvm allowing mixing of cg_clif and cg_llvm compiled crates and switching to the x64 cranelift backend based on the new backend framework.

Indicate both start and end of pass RSS in time-passes output
Previously, only the end of pass RSS was indicated. This could easily
lead one to believe that the change in RSS from one pass to the next was
attributable to the second pass, when in fact it occurred between the
end of the first pass and the start of the second.
Also, improve alignment of columns.
Sample of output:
```
time: 0.739; rss: 607MB -> 637MB item_types_checking
time: 8.429; rss: 637MB -> 775MB item_bodies_checking
time: 11.063; rss: 470MB -> 775MB type_check_crate
time: 0.232; rss: 775MB -> 777MB match_checking
time: 0.139; rss: 777MB -> 779MB liveness_and_intrinsic_checking

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: c5273bdfb2 That change is blocked on figuring out what to do with https://github.com/rust-lang/rust/issues/80846 first.
Fixes#81543
After we expand a macro, we try to parse the resulting tokens as a AST
node. This commit makes several improvements to how we handle spans when
an error occurs:
* Only ovewrite the original `Span` if it's a dummy span. This preserves
a more-specific span if one is available.
* Use `self.prev_token` instead of `self.token` when emitting an error
message after encountering EOF, since an EOF token always has a dummy
span
* Make `SourceMap::next_point` leave dummy spans unused. A dummy span
does not have a logical 'next point', since it's a zero-length span.
Re-using the span span preserves its 'dummy-ness' for other checks
Edit multiple error code Markdown files
Makes small edits to several error code files. Fixes some missing punctuation. Changes some wording, grammar, and formatting for clarity and readability.
Adds a link to the rustup book in E0658.
Don't link with --export-dynamic on wasm32-wasi
Remove --export-dynamic from the link arguments on the wasm32-wasi
target, as it emits spurious exports and increases code size.
Leave it in place for wasm32-unknown-unknown and
wasm32-unknown-emscripten. Even though it isn't a great solution
there, users are likely depending on its behavior there.
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.

codegen: assume constants cannot fail to evaluate

Clone entire `TokenCursor` when collecting tokens
Reverts PR #80830Fixestaiki-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.
