compile_sub_group_size is not implemented

[turinevgeny]

info::kernel_sub_group::compile_sub_group_size from sub_group_ndrange is not implemented:

: error: no member named 'compile_sub_group_size' in 'cl::sycl::info::kernel_sub_group'; did you mean 'kernel_sub_group_size'? cl::sycl::info::kernel_sub_group::compile_sub_group_size>(device); kernel_sub_group_size

Does anyone plan to fix it? Or I'd like to help. :)

@turinevgeny, I believe this issue is fixed by #373
