wcc/ww: paramfieldsize sizes a tagged-union destructure binding

Browse Source 
A tagged for-range destructure binding took the 8-byte default
(paramfieldsize had no tagged arm), skipping the full-extent copy —
the wwstage twin of the just-closed cstage destructure family. Read
the stamped tinfo size through the type table (twin of the slice
arm; cstage reads tp->type->size). Task #53.
