Subject: Allow to delay polymorphic opaque constants.

We had to move the private opaque constraints out of the constant declaration
into the opaque table. The API is not very pretty yet due to a pervasive
confusion between monomorphic global constraints and polymorphic local ones,
but once we get rid of futures in the kernel this should be magically solved.
