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:
