[Beignet] [PATCH 4/5] runtime: set CL_KERNEL_PREFERRED_WORK_GROUP_SIZE_MULTIPLE to kernel's SIMD_WIDTH.

It makes sense to set CL_KERNEL_PREFERRED_WORK_GROUP_SIZE_MULTIPLE to the corresponding SIMD size. Then it provides a way for intel's OCL application to get SIMD width at runtime and make some SIMD width dependant optimization possible. Signed-off-by: Zhigang Gong ---
