Various improvements in handling of evars in general and typing

2008-06-21T10:04:11+00:00

constraints in Program:
- normalize types and defs of local fixpoints before checking the
guardness condition to avoid having to give type annotations, e.g:
<<
Definition fold (A B : Set) (f : B -> A -> B) : B -> tree A -> B :=
  fix aux acc t :=
    match t with
      | Leaf x => f acc x
      | Node l => fold_left aux l acc
    end.
>>
- add new inh_coerce_to_prod to allow coercion of the typing constraint
to a product before trying to split it. It's a noop in standard mode, 
and forgets subsets in Program. Allows to typecheck:
<< (λ x, x) : { f : nat -> nat | ... } >>.
- Better handling of the "abstract" typing constraints in Program.
- Correctly normalize w.r.t. evars. the tycon given by users in Program.

Cleanup in subtac_cases, preparing to use improvements on return predicate

inference. Little improvement un subtac_obligations: do not retry to
solve all obligations when finishing to solve one obligation nobody
depends on.

Backport code from command.ml to subtac_command.ml for definining

recursive definitions. Now program accepts cofixpoints and uses the new
way infer structurally decreasing arguments. Also, checks for correct
recursive calls before giving the definition to the obligations machine
(solves part 1 of bug #1784).
