Refine Gregory Malecha's patch on VM and universe polymorphism.
- Universes are now represented in the VM by a structured constant containing the
global levels. This constant is applied to local level variables if any.
- When reading back a universe, we perform the union of these levels and return
a [Vsort].
- Fixed a bug: structured constants could contain local universe variables in
constructor arguments, which has to be prevented.
Was showing up for instance when evaluating [cons _ list (nil _)] with
a polymorphic [list] type.
- Fixed a bug: polymorphic inductive types can have an empty stack.
Was showing up when evaluating [bool] with a polymorphic [bool] type.
- Made a few cosmetic changes.
Patch written with Benjamin Grégoire.
