Bugfix #3431
Too strict checking in depsgraph code missed a dependency case; this specifically when objects have own motion (ipo) and are being deformed by a parent. This worked, unless the parent also had own motion (ipo or constraint)... Also: the DAG_add_relation() added multiple relationships for object pairs, now they "Or" the relationship description flag. Makes it a tad faster again :)
