Matthias Krüger 19437666d9 Rollup merge of #141724 - Sol-Ell:issue-141141-fix, r=nnethercote
fix(#141141): When expanding `PartialEq`, check equality of scalar types first.

Fixes rust-lang/rust#141141.

Now, `cs_eq` function of `partial_eq.rs` compares [scalar types](https://doc.rust-lang.org/rust-by-example/primitives.html#scalar-types) first.

- Add `is_scalar` field to `FieldInfo`.
- Add `is_scalar` method to `TyKind`.
- Pass `FieldInfo` via `CsFold::Combine` and refactor code relying on it.
- Implement `TryFrom<&str>` and `TryFrom<Symbol>` for FloatTy.
- Implement `TryFrom<&str>` and `TryFrom<Symbol>` for IntTy.
- Implement `TryFrom<&str>` and `TryFrom<Symbol>` for UintTy.

The rustc_ast crate contains those things concerned purely with syntax that is, the AST ("abstract syntax tree"), along with some definitions for tokens and token streams, data structures/traits for mutating ASTs, and shared definitions for other AST-related parts of the compiler (like the lexer and macro-expansion).

For more information about how these things work in rustc, see the rustc dev guide:
