`Lit::from_included_bytes` calls `Lit::from_lit_kind`, but the two call sites only need the resulting `token::Lit`, not the full `ast::Lit`. This commit changes those call sites to use `LitKind::to_token_lit`, which means `from_included_bytes` can be removed.
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:
