GBE: add ocl 2.0 work_group_barrier support

Graphics / Beignet - Ruiling Song [intel.com] - 8 November 2016 06:38 UTC

to do an image barrier, we need to: 1. flush L3 RW cache. 2. do a barrier gateway. 3. flush sampler cache.

Note the fence argument maybe ORed together. We need to support non-immediate barrier() argument in future.

v2: change syncField to 6, and modify syncStr.
