[flang] Fix constraint check on CLASS() entities

Entities declared with CLASS() must be dummy arguments, allocatables,
or pointers.  This constraint check is currently correct for objects
but not for procedures, and getting it right needs to avoid being
confused between pointers to procedures and pointers returned by
procedures.
