fixes #8916 by fixing typeinfo and marshal. (#9341)

* fixes #8916 by removing `tyString`, `tySeq`, mod. marshal, typeinfo

Need to check in `typeinfo` for nil of the underlying pointer.
In marshal don't have to check for nil of seq anymore.

* remove reference to string, sequence in `isNil` doc string
