Also wrap langtype::Type::Struct in an Rc

This makes copying such types much cheaper and will allow us to
intern common struct types in the future too. This further
drops the sample cost for langtype.rs from ~6.6% down to 4.0%.

We are now also able to share/intern common struct types.

  Range (min … max):    1.034 s …  1.105 s    10 runs

        allocations:            3074261
