[Beignet] [PATCH] Test case for missing global barrier functionality

[Dag Lem]

The attached test currently fails - I hope someone will take up the
gauntlet ;-)

I also see another problem with global memory - using a larger chunk
of global memory as temporary storage per work item (e.g. 64KB) seems
to trigger read/write inconsistency within each work item (reading
back zeros after having written non-zeros).
