When building a SYCL program targeting an AMD GPU that has a sub group size of 64, [[intel::reqd_sub_group_size(32)]] will cause compile error. Will you disable the generation of the attribute ?

@jinz2014 Could you try to change "[[intel::reqd_sub_group_size(32)]]" to "[[sycl::reqd_sub_group_size(32)]]", and could it be built pass?
