[PATCH] D27316: [CUDA] Filter out dirver sanitizer args for NVPTX

Before this patch, the following command would fail:

  clang++ -fsanitize=address --cuda-gpu-arch=sm_20 -c example.cu

with error:

  clang-4.0: error: unsupported option '-fsanitize=address' for target 'nvptx64-nvidia-cuda'

After this patch, there is no such compilation error.

I don't understand this part of the driver code very well, so I would appreciate any advice on whether this is the right way to fix this bug, and where would be the right place for me to put a test to check that it is working (i.e. ASAN still works for CUDA host code).
