CI: add script for installing NodeJS and update it to v20
I centralized the installation on a single place to make it simple to update the NodeJS version across the board.

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.
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 https://github.com/rust-lang/rust/pull/119427#discussion_r1439481201. 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()`).
Add llvm-bitcode-linker to build manifest
When creating #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.

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.

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.
Unblocks #123680
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.
Add a lower bound check to `unicode-table-generator` output
This adds a dedicated check for the lower bound
(if it is outside of ASCII range) to the output of the `unicode-table-generator` tool.
This generalized the ASCII-only fast-path, but only for the `Grapheme_Extend` property for now, as that is the only one with a lower bound outside of ASCII.
This handles using deref patterns to choose the correct match arm. This
does not handle bindings or guards.

PatRangeBoundary::compare_with: als add a fast-path for signed integers
Not sure if we have a benchmark that hits this... but it seems odd to only do this for unsigned integers.
