[Beignet] [PATCH 1/4] Add atomic help functions.

[Zhigang Gong]

Rong,

So after this patchset, we should already support the following extensions:
cl_khr_global_int32_base_atomics, cl_khr_global_int32_extended_atomics,
cl_khr_local_int32_base_atomics and cl_khr_local_int32_extended_atomics

Right? If so, could you also make a patch to add those extension string to
beignet's runtime library? Thanks.
