Alexey Bataev bb55ece269 [OPENMP][NVPTX]Relax flush directive. ... Summary: According to the OpenMP standard, flush makes a thread’s temporary view of memory consistent with memory and enforces an order on the memory operations of the variables explicitly specified or implied. According to the Cuda toolkit documentation (https://docs.nvidia.com/cuda/archive/8.0/cuda-c-programming-guide/index.html#memory-fence-functions), __threadfence() functions provides required functionality. __threadfence_system() also provides required functionality, but it also includes some extra functionality, like synchronization of page-locked host memory, synchronization for the host, etc. It is not required per the standard and we can use more relaxed version of memory fence operation.
