norecurse function attr indicates the function is not called recursively directly or indirectly. Add norecurse to OpenCL functions, SYCL functions in device compilation and CUDA/HIP kernels. Although there is LLVM pass adding norecurse to functions, it only works for whole-program compilation. Also FE adding norecurse can make that pass run faster since functions with norecurse do not need to be checked again. Differential Revision: https://reviews.llvm.org/D73651
