Migrate rustc_monomorphize to use SessionDiagnostic ### Description - Migrates diagnostics in `rustc_monomorphize` to use `SessionDiagnostic` - Adds an `impl IntoDiagnosticArg for PathBuf` ### TODO / Help! - [x] I'm having trouble figuring out how to apply an optional note. 😕 Help!? - Resolved. It was bad docs. Fixed in https://github.com/rust-lang/rustc-dev-guide/pull/1437/files - [x] `errors:RecursionLimit` should be `#[fatal ...]`, but that doesn't exist so it's `#[error ...]` at the moment. - Maybe I can switch after this is merged in? --> https://github.com/rust-lang/rust/pull/100694 - Or maybe I need to manually implement `SessionDiagnostic` instead of deriving it? - [x] How does one go about converting an error inside of [a call to struct_span_lint_hir](8064a49508/compiler/rustc_monomorphize/src/collector.rs (L917-L927))? - [x] ~What placeholder do you use in the fluent template to refer to the value in a vector? It seems like [this code](0b79f758c9/compiler/rustc_macros/src/diagnostics/diagnostic_builder.rs (L83-L114)) ought to have the answer (or something near it)...but I can't figure it out.~ You can't. Punted.
