ca075d268d Auto merge of #83386 - mark-i-m:stabilize-pat2015, r=nikomatsakis 
Stabilize `:pat_param` and remove `:pat2021`

Blocked on #83384

cc `@rust-lang/lang` #79278

If I understand `@nikomatsakis` in  https://rust-lang.zulipchat.com/#narrow/stream/213817-t-lang/topic/or.20patterns/near/231133873, another FCP is not needed.

3ea62cb5d1 Remove redundant ignore-tidy-linelength annotations 
This is step 2 towards fixing #77548.

In the codegen and codegen-units test suites, the `//` comment markers
were kept in order not to affect any source locations. This is because
these tests cannot be automatically `--bless`ed.

Rollup merge of #83348 - osa1:issue83344, r=jackh726 
format macro argument parsing fix

When the character next to `{}` is "shifted" (when mapping a byte index
in the format string to span) we should avoid shifting the span end
index, so first map the index of `}` to span, then bump the span,
instead of first mapping the next byte index to a span (which causes
bumping the end span too much).

Regression test added.

Fixes #83344

Stabilize or_patterns (RFC 2535, 2530, 2175)

closes #54883

This PR stabilizes the or_patterns feature in Rust 1.53.

This is blocked on the following (in order):
- [x] The crater run in https://github.com/rust-lang/rust/pull/78935#issuecomment-731564021
- [x] The resolution of the unresolved questions and a second crater run (https://github.com/rust-lang/rust/pull/78935#issuecomment-735412705)
    - It looks like we will need to pursue some sort of edition-based transition for `:pat`.
- [x] Nomination and discussion by T-lang
- [x] Implement new behavior for `:pat` based on consensus (https://github.com/rust-lang/rust/pull/80100).
- [ ] An FCP on stabilization

796ce9fcb7 Suggest returning tail expressions that match return type 
Some newcomers are confused by the behavior of tail expressions,
interpreting that "leaving out the `;` makes it the return value".
To help them go in the right direction, suggest using `return` instead
when applicable.

cb653b100c Document that assert! format arguments are evaluated lazily 
It can be useful to do some computation in `assert!` format arguments, in order to get better error messages. For example:

```rust
assert!(
    some_condition,
    "The state is invalid. Details: {}",
    expensive_call_to_get_debugging_info(),
);
```

It seems like `assert!` only evaluates the format arguments if the assertion fails, which is useful but doesn't appear to be documented anywhere. This PR documents the behavior and adds some tests.

a616f8267e Add lint for panic!(123) which is not accepted in Rust 2021. 
This extends the `panic_fmt` lint to warn for all cases where the first
argument cannot be interpreted as a format string, as will happen in
Rust 2021.

It suggests to add `"{}", ` to format the message as a string. In the
case of `std::panic!()`, it also suggests the recently stabilized
`std::panic::panic_any()` function as an alternative.

It renames the lint to `non_fmt_panic` to match the lint naming
guidelines.

Implement edition-based macro :pat feature

This PR does two things:
1. Fixes the perf regression from https://github.com/rust-lang/rust/pull/80100#issuecomment-750893149
2. Implements `:pat2018` and `:pat2021` matchers, as described by `@joshtriplett`  in https://github.com/rust-lang/rust/issues/54883#issuecomment-745509090 behind the feature gate `edition_macro_pat`.
