Constructor type information uses the expanded form.
It used to simply remember the normal form of the type of the constructor.
This is somewhat problematic as this is ambiguous in presence of
let-bindings. Rather, we store this data in a fully expanded way, relying
on rel_contexts.
Probably fixes a crapload of bugs with inductive types containing
let-bindings, but it seems that not many were reported in the bugtracker.
