The idea being out-syncs can signal indicating all previous operations on the bind queue are complete. An example use case of this would be support for implementing vkQueueWaitIdle easily. All in-syncs are waited on before signaling out-syncs. This is implemented by forming a composite software fence of in-syncs and installing this fence in the out-syncs and exec queue last fence slot. The last fence must be added as a dependency for jobs on user exec queues as it is possible for the last fence to be a composite software fence (unordered, ioctl with zero bb or binds) rather than hardware fence (ordered, previous job on queue).
