Relatively ad hoc fix to an ill-typed instantiation bug in type
inference (see file failure/evar1.v) + fix of some CUMUL problems that
were in the wrong direction. We assume for the fix that ill-typed
unification problems come from subtyping where we don't know yet if a
coercion has to be inserted or not, and hence are of the CUMUL
form. More on suspending problems of the form ?n <= Type or Prop <= ?n
has to be done yet.
