414b8b98 - [CodeGen][Transforms] Remove unused DenseMapInfo::getTombstoneKey (#200956)

[CodeGen][Transforms] Remove unused DenseMapInfo::getTombstoneKey (#200956) #200595 changed DenseMap to no longer create tombstone buckets, so DenseMapInfo<T>::getTombstoneKey() is never called. Remove dead definitions and dead tombstone branches.
