Sort them, and remove the unused ones (`lint_reasons` and `proc_macro_span`).
They each have a single call site.
Control flow never gets past the end of the `ExpandResult::Retry` match arm, due to the `span_bug` and the `continue`. Therefore, the code after the match can only be reached from the `ExpandResult::Ready` arm. This commit moves that code after the match into the `ExpandResult::Ready` arm, avoiding the need for the `continue` in the `ExpandResult::Retry` arm.
Too clever by half, IMO.
Alongside the existing `Invocation::span`.
Because the type is not obvious, and this clarifies things.
It is currently an enum and the `tts` and `idx` fields are repeated across the two variants. This commit splits it into a struct `Frame` and an enum `FrameKind`, to factor out the duplication. The commit also renames `Frame::new` as `Frame::new_delimited` and adds `Frame::new_sequence`. I.e. both variants now have a constructor.
