Thank you LLVM guys. We have chance to rescue the CUDA package.

Proposed fix for CUDA is attached. Not carefully tested yet.
CUDA 8.0 supports Clang up to 3.8 (clang <= 3.8). [1]

caffe-contrib's default compiler has been changed to
clang-3.8 several weeks ago. I don't know whether
the other CUDA applications compile with Clang.

[1] conclusion made from caffe-contrib compiling experiments.

+  The recommended compiler for CUDA 8.0 has been changed from GCC-5 to
