configure: Fix cross-compiling LLVM for realz
Actually got it working this time, and it was again just a problem specifying
the llvm-tblgen binary. We need to point it at the $CFG_BUILD target's tblgen
and then we also needed to correct the path a bit.

Disable debuginfo tests for a given blacklist of LLDB versions
Anyone having trouble with most LLDB tests failing on OSX, please report your LLDB version here so I can add it to the blacklist.
Blacklisted versions so far:
* lldb-350.*
cc @rust-lang/tools
cc @tedhorst @indutny @jonathandturner (people from the original bug report)
Fixes#32520.
Revert "skip double negation in const eval"
This reverts commit 735c018974.
fixes#34395
The original commit was based on a mis-understanding of the overflowing literal lint.
This needs to be ported to beta.

Forbid type parameters and global paths in macro invocations
Fixes#28558.
This is a [breaking-change]. For example, the following would break:
```rust
macro_rules! m { () => { () } }
fn main() {
m::<T>!(); // Type parameters are no longer allowed in macro invocations
::m!(); // Global paths are no longer allowed in macro invocations
}
```
Any breakage can be fixed by removing the type parameters or the leading `::` (respectively).

Give `ast::ExprKind::Paren` no-op expressions the same ids as their children.
Having `ast::ExprKind::Paren` expressions share ids with their children
- reduces the number of unused `NodeId`s in the hir map and
- guarantees that `tcx.map.expect_expr(ast_expr.id)` is the hir corresponding to `ast_expr`.
This fixes the bug from #34327, which was introduced in #33296 when I assumed the above guarantee.

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
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)
