Fix errors and warnings with CUDA 9.0 builds - #2923

Sorry, something went wrong.
* The rdc and dlink flags are not required because they are added by CMake for separable compilation and static linking respectively * Add guards around libs that are not included in the CUDA 9.0 Toolkit * Only link with OpenMP when linking with cuSOLVER dynamically * Fix error message when CUDNN is not found
* Address casts from double to __half which are missing in 9.0 * Thrust return_temporary_buffer function can accept void* pointers in older versions of Thrust. Use raw_pointer_cast to pass the pointer to memFree * cublasGemmEx doesn't exist in CUDA 9.0. Add ifdefs to guard against older builds * __float2half is not a host function so it needs to be removed from mean * Add template instantiation for memFree to accept void* pointers
CUSOLVER_CHECK error message printed "CUBLAS Error" instead of CUSOLVER Error

I have checked with toolkits 10 with separable ON and OFF on my system again just to be sure. Surprisingly it does work without the flags. I clearly remember it giving issues earlier. Perhaps, the reorganization I did w.r.t sources of cuda::{thrus,scan} and the static lib cleared out an indirect issue.

Makes sense, these are not there prior to toolkit 10 - I should have thought about this

nit: I think a better check to avoid any unexpected issues (with decimals and all against different cmake versions) with cmake is to do
if(CUDA_VERSION_MAJOR VERSION_GREATER 9)On another note, I will take care of this with some other change.

nit: looks like this is just to make the compiler silent even though this won't be actually inlined.
