  -----------
  Remove use of tuple for multiresult type storage

Move the results in line with the op instead. This results in each
operation having its own types recorded vs single tuple type, but comes
at benefit that every mutation doesn't incurs uniquing. Ran into cases
where updating result type of operation led to very large memory usage.
