Preliminary CUDA Half support (#1808)

* #include an absolute path didn't work - because paths were taken to always be relative.

* WIP CUDA half support.

* Working support for half on CUDA - requires cuda_fp16.h and associated files can be found.

* Fix for win32 for unused funcs.

* Fix for Clang.

* Hack to disable unused local function warning.
