Bugfix #3431

Browse Source 
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 :)
