Instead of calling CUDA runtime to arrange function arguments, the new API constructs arguments in a local array and the kernels are launched with __cudaLaunchKernel(). The old API has been deprecated and is expected to go away in the next CUDA release. Differential Revision: https://reviews.llvm.org/D57488 llvm-svn: 352799
