Try to fix the nightlies
They look to be failing right after the CMake PR landed. I've diagnosed and confirmed the first issue fixed, the second is a bit of a shot in the dark to see if it fixes things.
Add example with leading zeros
I was searching for this format very long. So I added an example to the prominent section.
I was thinking of putting the keyword leading in the corresponding section as well, what do you think?

[doc] Fix links in Ownership section of the book
- Add a missing link definition for `[i32]`.
- Like `[stack]` link is pointing to `...#the-stack`, append `#the-heap` to `[heap]` link.
Syntax coloring and more compact diagram
Two cosmetic improvements:
- New content was added a few days ago to the **Closures** chapter but it was missing rust's syntax coloring.
- Also, in the **Crates and Modules** chapter, a diagram was improved to be more symmetric and to take less space.
* Implement the clean-llvm target for those cases where makefiles are being used
* Have all cross-compiled LLVMs depend on the **host** LLVM as they'll require
the llvm-tablegen executable from there
The LLVM build system is somewhat picky about which Python is used to build it
as it's known to be incompatible with the default `python2` package that ships
with MinGW. This was previously detected for MSVC builds but the logic was left
out for MinGW by accident (now that we've switched to cmake builds for LLVM
everywhere).
This corrects the `./configure` check and also updates the `README.md`
accordingly. Additionally, a number of instructions were updated to work with
the most recent copy of MSYS2.
Closes#34489
Batch up libsyntax breaking changes
Batch of the following syntax-[breaking-change] changes:
- #34213: Add a variant `Macro` to `TraitItemKind`
- #34368: Merge the variant `QPath` of `PatKind` into the variant `PatKind::Path`
- #34385: Move `syntax::ast::TokenTree` into a new module `syntax::tokenstream`
- #33943:
- Remove the type parameter from `visit::Visitor`
- Remove `attr::WithAttrs` -- use `attr::HasAttrs` instead.
- Change `fold_tt`/`fold_tts` to take token trees by value and avoid wrapping token trees in `Rc`.
- Remove the field `ctxt` of `ast::Mac_`
- Remove inherent method `attrs()` of types -- use the method `attrs` of `HasAttrs` instead.
- #34316:
- Remove `ast::Decl`/`ast::DeclKind` and add variants `Local` and `Item` to `StmtKind`.
- Move the node id for statements from the `StmtKind` variants to a field of `Stmt` (making `Stmt` a struct instead of an alias for `Spanned<StmtKind>`)
- Rename `ast::ExprKind::Again` to `Continue`.
- #34339: Generalize and abstract `ThinAttributes` to `ThinVec<Attribute>`
- Use `.into()` in convert between `Vec<Attribute>` and `ThinVec<Attribute>`
- Use autoderef instead of `.as_attr_slice()`
- #34436: Remove the optional expression from `ast::Block` and instead use a `StmtKind::Expr` at the end of the statement list.
- #34403: Move errors into a separate crate (unlikely to cause breakage)
grammatical: "Here's" should be "Here are", "rules" is plural.
stylistic: "rules for" is more idiomatic than "rules about".
grammatical: No verb in "One or the other"; changed to "It's one or the other".
code: added implied `fn main() { ... }` because it is referenced in "note: previous borrow ends here"
semantic: "But" seems like the wrong word here, there is now, contrast, only further explanation. "so", "thus" or "therefor" is clearer.
grammatical: Another misuse of "Here's", should be "Here are" (or possibly "Here're").
grammatical: "use" should be capitalized. All other subheadings capitalize the first word.
[MIR] Add Dominators to MIR and Add Graph Algorithms
~~This PR assumes PR #34149 lands.~~
Add generic graph algorithms to rustc_data_structures.
Add dominators and successors to the ~~cache (that currently only holds predecessors).~~ `Mir`.
