[Beignet] [PATCH 0/2] Fix the barrier related bugs.

[Zhigang Gong]

We have two known issues which are barrier related.
1. The compiler_local_memory_barrier_2 need to add a memory fence for local memory barrier which is not comply with
Gen7 spec.
2. The compiler_global_memory_barrier fails on GT1 with SIMD8 mode, and if we increase the local size to 256, it also
fails on GT7 machine.

This patchset fixes all the above issue.


Zhigang Gong (2):
  GBE: fixed a barrier related bug.
  utests: increase local size in the two barrier test cases.
