    }

Required for being able to make the fields private and force the use of
accessor methods, which will be added in the next commit.

static_mut_refs: use raw pointers to remove the remaining FIXME

Using `SyncUnsafeCell` would not make a lot of sense IMO.

Use fake libc in core test

The war on libc continues.

Some platforms may not need to link to the libc crate (and it's possible some may not even have a libc), therefore we shouldn't require it for tests. This creates dummy `malloc` and `free` implementations for use in the pointer docs, but, keeps the public documentation looking the same as before.

lint-docs: Add redirects for renamed lints.

This updates the lint docs to include a redirect for renamed lints to the new name. This helps ensure that links to the old name will still be valid.

Note that this currently uses a hard-coded list. As mentioned in the comment, a future enhancement may gather this information in a better way.

coverage: Branch coverage tests for lazy boolean operators

The current branch coverage implementation already supports the `&&` and `||` operators (even outside of an `if` condition), as a natural consequence of how they are desugared/lowered, but we didn't have any specific tests for them. This PR adds some appropriate tests.

I've also moved the existing branch coverage tests into a `coverage/branch` subdirectory, so that they don't become unwieldy as I add more branch coverage tests.

Add llvm-bitcode-linker to build manifest

When creating rust-lang#123423 I didn't realize I also had to add the new component to the build-manifest. This PR finishes the work of adding it, by also adding it to the build manifest.

Improve std::fs::Metadata Debug representation

- Remove duplication of `mode` between `file_type` and `permissions`, which both involve operating on the same mode_t integer
- Add `is_symlink`
- Add `len` in bytes
- Remove Ok wrapping around `modified`, `accessed`, `created`, which eliminates 6 useless lines

llvm RustWrapper: explain OpBundlesIndirect argument type

Follow-up to rust-lang#123941

r? ``@Mark-Simulacrum``

Give a name to each distinct manipulation of pretty-printer FixupContext

There are only 7 distinct ways that the AST pretty-printer interacts with FixupContext: 3 constructors (including Default), 2 transformations, and 2 queries.

This PR turns these into associated functions which can be documented with examples.

This PR unblocks rust-lang#119427 (comment). In order to improve the pretty-printer's behavior regarding parenthesization of braced macro calls in match arms, which have different grammar than macro calls in statements, FixupContext needs to be extended with 2 new fields. In the previous approach, that would be onerous. In the new approach, all it entails is 1 new constructor (`FixupContext::new_match_arm()`).

mir-opt tests: rename unit-test -> test-mir-pass

"unit-test" is extremely non-descriptive, no idea how one is supposed to read that and know that this specifies the MIR pass being tested.
