Log:
[CUDA][Clang][Bugfix] Add missing CUDA 9.2 case

Summary:
The bug was reported on the OpenMP-dev list:

.../obj-release/lib/clang/9.0.0/include/__clang_cuda_intrinsics.h:173:35: error: '__nvvm_shfl_sync_idx_i32' needs target feature ptx60|ptx61|ptx63|ptx64
__MAKE_SYNC_SHUFFLES(__shfl_sync, __nvvm_shfl_sync_idx_i32,

This problem occurs when trying to compile a .cu file that requires a newer ptx version (>ptx60 in this case) than ptx42.
