395ee0b79f Introduce rustc_lexer 
The idea here is to make a reusable library out of the existing
rust-lexer, by separating out pure lexing and rustc-specific concerns,
like spans, error reporting an interning.

So, rustc_lexer operates directly on `&str`, produces simple tokens
which are a pair of type-tag and a bit of original text, and does not
report errors, instead storing them as flags on the token.

Fix #62660

If the explicitly given type of a `self` parameter fails to parse correctly, we need to propagate the error rather than dropping it and causing an ICE.

Fixes #62660.

4edff843dd Auto merge of #61347 - Centril:stabilize-underscore_const_names, r=petrochenkov 
Stabilize underscore_const_names in 1.37.0

You are now permitted to write:

```rust
const _: $type_expression = $term_expression;
```

That is, we change the [grammar of items](9d1984d7ae/grammar/item.lyg (L3-L42)), as written in [the *`.lyg`* notation](263bf161da (grammar)), from:

```java
Item = attrs:OuterAttr* vis:Vis? kind:ItemKind;
ItemKind =
  | ...
  | Const:{ "const" name:IDENT ":" ty:Type "=" value:Expr ";" }
  | ...
  ;
```

into:

```java
Item = attrs:OuterAttr* vis:Vis? kind:ItemKind;
ItemKind =
  | ...
  | Const:{ "const" name:IdentOrUnderscore ":" ty:Type "=" value:Expr ";" }
  | ...
  ;

IdentOrUnderscore =
  | Named:IDENT
  | NoName:"_"
  ;

Allow attributes in formal function parameters

Implements https://github.com/rust-lang/rust/issues/60406.

This is my first contribution to the compiler and since this is a large and complex project, I am not fully aware of the consequences of the changes I have made.

**TODO**

- [x] Forbid some built-in attributes.
- [x] Expand cfg/cfg_attr

5e2c11034f Auto merge of #60793 - Xanewok:raw-string-cleanup, r=petrochenkov 
lexer: Disallow bare CR in raw byte strings

Handles bare CR ~but doesn't translate `\r\n` to `\n` yet in raw strings yet~ and translates CRLF to LF in raw strings.

As a side-note I think it'd be good to change the `unescape_` to return plain iterators to reduce some boilerplate (e.g. `has_error` could benefit from collecting `Result<T>` and aborting early on errors) but will do that separately, unless I missed something here that prevents it.

@matklad @petrochenkov thoughts?
