Fix #35829 (`quote!()` does not handle `br#"…"#`)

Fix issue #35829 (syntax extension's `quote_expr!()` does not handle `b"…"` and proc_macro's `quote!()` does not handle `r#"…"#`)

* Handles `b"…"`, `br#"…"#` and `...` for `quote_expr!()`.
* Refactored the match statement to allow it to complain loudly on any unhandled token.
* Similarly, proc_macro's `quote!()` did not handle `br#"…"#` or `r#"…"#`, so this PR fixes it too.

Document the `proc_macro` feature in the Unstable Book

Discusses the `proc_macro` feature flag and the features it enables:

* Implicit enable of `extern_use_macros` feature and how to import proc macros
* Error handling in proc macros (using panic messages)
* Function-like proc macros using `#[proc_macro]` and a usage example for creating and invoking
* Attribute-like proc macros using `#[proc_macro_attribute]` and a usage example for creating and invoking

52abafa464 Rollup merge of #42017 - nikomatsakis:issue-41677, r=arielb1
avoid cycles in mir-dump, take 2

This fixes #41697, for real this time, but I'm not sure how best to add a regression test. I was considering maybe adding some flag so that the MIR dumping doesn't actually get written to files (e.g., overloading the directory flag so you can specify nil or something).

8f61055c52 Rollup merge of #41937 - nikomatsakis:issue-41936-variance-coerce-unsized-cycle, r=eddyb
use equality in the coerce-unsized check

This seems both to be a safe, conservative choice, and it sidesteps the cycle in #41849. Note that, before I converted variance into proper queries, we were using a hybrid of subtyping and equality, due to the presence of a flag that forced invariance if variance had not yet been computed. (Also, Coerce Unsized is unstable.)

Fixes #41936.

Add lint for unused macros

Addresses parts of #34938, to add a lint for unused macros.

We now output warnings by default when we encounter a macro that we didn't use for expansion.

Issues to be resolved before this PR is ready for merge:

- [x] fix the NodeId issue described above
- [x] remove all unused macros from rustc and the libraries or set `#[allow(unused_macros)]` next to them if they should be kept for some reason. This is needed for successful boostrap and bors to accept the PR. -> #41934
- [x] ~~implement the full extent of #34938, that means the macro match arm checking as well.~~ *let's not do this for now*

improve collapse toggle render (css)

The `[-]` toggle for functions in docs _seems_ too big. It's just an impression, but it's something I noticed long time ago (maybe I have bad taste). I never thought to fix it, but, today I think: "Ok, why not suggest it.". Feel free to close without explanation!

fa78d5bb87 Auto merge of #41565 - rkruppe:llvm-sys, r=eddyb
Make only rustc_trans depend on rustc_llvm

With these changes, only rustc_trans depends directly on rustc_llvm (and no crate gained a new dependency on trans). This means changing LLVM doesn't rebuild librustc or rustc_metadata, only rustc_trans, rustc_driver and the rustc executable
Also, rustc_driver technically doesn't know about LLVM any more (of course, it still handles a ton of options that conceptually refer to LLVM, but it delegates their implementation to trans).

What I *didn't* implement was merging most or all of rustc_llvm into rustc_trans. I ran into a nasty bug, which was probably just a silly typo somewhere but I probably won't have the time to figure it out in the next week or two. I opened #41699 for that step.

Fixes #41473

Update to the Rusty rust-installer

This updates the rust-installer submodule to the new version written in Rust (rust-lang/rust-installer#62), now moved to `src/tools/rust-installer` and invoked in `dist.rs` as a cargo-based tool command.  All of the former shell-script invocations now invoke the tool, otherwise keeping the same arguments as before.

As a small bonus, `rustc-src` now also uses the same tarball generator, so it gains a smaller `.tar.xz` too.

Fixes #41569.  r? @alexcrichton
