Shilei Tian 7cc27af3c6 [AbstractAttributor] Fold function calls to __kmpc_is_spmd_exec_mode if possible ... In the device runtime there are many function calls to `__kmpc_is_spmd_exec_mode` to query the execution mode of current kernels. In many cases, user programs only contain target region executing in one mode. As a consequence, those runtime function calls will only return one value. If we can get rid of these function calls during compliation, it can potentially improve performance. In this patch, we use `AAKernelInfo` to analyze kernel execution. Basically, for each kernel (device) function `F`, we collect all kernel entries `K` that can reach `F`. A new AA, `AAFoldRuntimeCall`, is created for each call site. In each iteration, it will check all reaching kernel entries, and update the folded value accordingly. In the future we will support more function.
