Patch to allow VS2015 & CUDA 8.0 to compile with Eigen included. I'm not sure
...
whether to limit the check to this compiler combination
(` || (EIGEN_COMP_MSVC == 1900 && __CUDACC_VER__) `)
or to leave it as it is. I also don't know if this will have any affect on
including Eigen in device code (I'm not in my current project).
