* When encountering EOF, point at the last opening brace that does not have the same indentation level as its close delimiter. * When encountering the wrong type of close delimiter, point at the likely correct open delimiter to give a better idea of what went wrong.

refactor match guard This is the first step to implement RFC 2294: if-let-guard. Tracking issue: https://github.com/rust-lang/rust/issues/51114 The second step should be introducing another variant `IfLet` in the Guard enum.

set cfg(rustdoc) when rustdoc is running on a crate When using `#[doc(cfg)]` to document platform-specific items, it's a little cumbersome to get all the platforms' items to appear all at once. For example, the standard library adds `--cfg dox` to rustdoc's command line whenever it builds docs, and the documentation for `#![feature(doc_cfg)]` suggests using a Cargo feature to approximate the same thing. This is a little awkward, because you always need to remember to set `--features dox` whenever you build documentation. This PR proposes making rustdoc set `#[cfg(rustdoc)]` whenever it runs on a crate, to provide an officially-sanctioned version of this that is set automatically. This way, there's a standardized way to declare that a certain version of an item is specifically when building docs. To try to prevent the spread of this feature from happening too quickly, this PR also restricts the use of this flag to whenever `#![feature(doc_cfg)]` is active. I'm sure there are other uses for this, but right now i'm tying it to this feature. (If it makes more sense to give this its own feature, i can easily do that.)

Stabilize a few secondary macro features - `tool_attributes` - closes https://github.com/rust-lang/rust/issues/44690 - `proc_macro_path_invoc` - this feature was created due to issues with tool attributes (https://github.com/rust-lang/rust/issues/51277), those issues are now fixed (https://github.com/rust-lang/rust/pull/52841) - partially `proc_macro_gen` - this feature was created due to issue https://github.com/rust-lang/rust/issues/50504, the issue is now fixed (https://github.com/rust-lang/rust/pull/51952), so proc macros can generate modules. They still can't generate `macro_rules` items though due to unclear hygiene interactions.

Feature gate where clauses on associated type impls Fixes #52913. This doesn't address the core problem, which is tracked by https://github.com/rust-lang/rust/issues/47206. However, it fixes the stable-to-stable regression: you now have to enable `#![feature(generic_associated_types)]` to trigger the weird behaviour.

oli-obk:dont_you_hate_it_too_when_everything_panics_constantly, r=eddyb Allow panicking with string literal messages inside constants r? @eddyb cc https://github.com/rust-lang/rust/issues/51999 we can't implement things like `panic!("foo: {}", x)` right now because we can't call trait methods (most notably `Display::fmt`) inside constants. Also most of these impls probably have loops and conditions, so it's messy anyway. But hey `panic!("foo")` works at least. cc @japaric got any test ideas for `#![no_std]`?
