General idea is to avoid actual calculation from property update() callback and tag things for update later instead. That said, pose constraint flags are now tagged for update and handled as a part of object update. In the new depsgraph it'll be a nice dedicated operation node. Also avoid updating disabled flags for all the modifiers. This part of the path is not totally optimal since it'll still need to iterate over bones in order to get pchan, but to optimize it further would be nice to find a way to avoid pchan requirement all together.
