A constr which is Hint'ed will be:

push_resolve_hyp hname htyp db. used to add an hypothesis to the local hint database; Never raises a user exception; If the hyp cannot be used as a Hint, it is not added.

val push_resolve_hyp : Environ.env -> Evd.evar_map -> Names.Id.t -> Hint_db.t -> Hint_db.t

Create a Hint database from the pairs (name, constr). Useful to take the current goal hypotheses as hints; Boolean tells if lemmas with evars are allowed
