This fix is needed for #1179. Currently ocloc installed in CRI environment as a part of NEO has support only for CRI architecture and no other GPUs are recognized by it, so this is a quick change to allow benchmarks to build for CRI. --------- Signed-off-by: Gregory Shimansky <gregory.shimansky@intel.com>

The
gen.sub_group_reduceoperation is invoked by all work items in a subgroup, each of them providing a $value. The $size argument is used to form groups of $size consecutive work items called clusters. Each cluster performs the reduction operation identified by $kind. The result of the cluster reduction is propagated to the work items belonging to that cluster.It lowers to either WaveAll or WaveClustered depending on the given size.
