  Log Message:
  -----------
  [IR] Remove obsolete visited sets from type queries (NFC) (#221743)

Recursive types have been rejected since 2024 (#114799), making the
visited sets in type queries unnecessary.

Improves CTMark geomean -0.08% on aarch64-O0-g. Also improves
compile-time slightly for several other targets.
