IMPALA-11323: Don't evaluate constants-only inferred predicates

Browse Source 
IMPALA-10182 fixed the problem of creating inferred predicates when
both sides of an equality predicate came from the same slot.

Inferred predicates also should not be created when both sides
of an equality predicate are constant values which do not have
scan slots.
