By naming them in `[workspace.lints.rust]` in the top-level
`Cargo.toml`, and then making all `compiler/` crates inherit them with
`[lints] workspace = true`. (I omitted `rustc_codegen_{cranelift,gcc}`,
because they're a bit different.)
The advantages of this over the current approach:
- It uses a standard Cargo feature, rather than special handling in
bootstrap. So, easier to understand, and less likely to get
accidentally broken in the future.
- It works for proc macro crates.
It's a shame it doesn't work for rustc-specific lints, as the comments
explain.
It was added in #129523 to enable building on stable when there were
`cfg(bootstrap)` occurrences in the crate. But those are gone now, so
the section can be removed.
Use `std::mem::{size_of, size_of_val, align_of, align_of_val}` from the
prelude instead of importing or qualifying them.
These functions were added to all preludes in Rust 1.80.

The `max_line_length` property was set to 100 for all filetypes, which
led to git commit messages being wrapped at 100 characters instead of
the usual 75. This introduces an exception for the special file used by
git to write commit messages.

A new syntax node `ast::VariantDef` has been introduced to map between the HIR node and the AST.
The files have been updated with `cargo test -p xtask`.

Clean up various LLVM FFI things in codegen_llvm
cc ```@ZuseZ4``` I touched some autodiff parts
The major change of this PR is [bfd88ce](bfd88cead0) which makes `CodegenCx` generic just like `GenericBuilder`
The other commits mostly took advantage of the new feature of making extern functions safe, but also just used some wrappers that were already there and shrunk unsafe blocks.

Change the way that underline positions are calculated by delaying using
the "visual" column position until the last possible moment, instead
using the "file"/byte position in the file, and then calculating visual
positioning as late as possible. This should make the underlines more
resilient to non-1-width unicode chars.
Unfortunately, as part of this change (which fixes some visual bugs)
comes with the loss of some eager tab codepoint handling, but the output
remains legible despite some minor regression on the "margin trimming"
logic.
When encountering a single line span that is wider than the terminal, we keep context at the start and end of the span but otherwise remove the code from the middle. This is somewhat independent from whether the left and right margins of the output have been trimmed as well.

Address part of #137680 (missing handling of the long suggestion). Fix#125581.
`-Zteach` is perma-unstable, barely used, the highlighting logic buggy and the flag being passed around is tech-debt. We should likely remove `-Zteach` in its entirely.
This already works for --emit=metadata, but is possible anytime we're not
linking.
Tests:
`rmeta_bin` checks we're not changing --emit=link (already passes)
`rmeta_bin-pass` tests the new behavior for --emit=obj (would fail today)
and also --emit=metadata which isn't changing
use target compiler on llvm-bitcode-linker
The build compiler is already resolved inside the `ToolBuild` step, so we should pass only the target compilers for `Mode::ToolRustc` tools.

A check for `#[non_exhaustive]` is often done in combination with
checking whether the type is local to the crate, in a variety of ways.
Create a helper method and standardize on it as the way to check for
this.
