Introducing a notion of evar candidates to be used when an evar is
known in advance to be instantiable by only a finite number of terms.
When an evar with candidates remain unsolved after unification, the
first candidate is taken as a heuristic.
This is used in particular to reduce the number of pending conversion
problems when trying to infer the return clause of a pattern-matching
problem. As an example, this repairs test 2615.v.
