//! Diagnostic emission for the consumed-literal violations the
//! pre-expansion pass discovers. The late `ExprKind::Lit` path emits its
//! own diagnostics inline via `span_lint_and_sugg`; this helper is the
//! HIR-anchored counterpart for the queued ones, drained at
//! `check_crate_post`. Message, label, and applicability match the
//! inline path exactly so the two firing routes are indistinguishable
//! to the user.
