A new function attribute named amdgpu_num_work_groups is added. This attribute, which consists of three integers, allows programmers to let the compiler know the number of workgroups to be launched in each of the three dimensions and do optimizations based on that information. --------- Co-authored-by: Jun Wang <jun.wang7@amd.com>
