[PATCH] D21723: [RFC] Enhance synchscope representation

This direction is interesting and would definitely help GPU devices.  The metadata approach in the original proposal worried me a bit - I'm glad to see this implementation instead.

Have you considered a named syncscope of System or SoC?  This would be similar to the OpenCL 2.0 all_devices scope, but generic enough that I think it could be useful in other domains.  Even as is, I would take advantage of these changes.
