rustbuild: Clean out tmp directory on `make clean`
Right now we generate error index information into this directory, but it's
never cleaned out. This means that if a build *bounces* because of something in
this directory it'll continue to cause all future builds to fail because the
relevant files are never removed.

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.*

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.

rustdoc: Remove Derived Implementations title
As far as I know whether a trait was derived or not does not change the
public API so there is no need to include this information in the docs.
This title currently just adds an extra divide in the list of trait
implementations which I don't think needs to be there.
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.
