* PTX kernel argument buffer now has naturally aligned arguments as required by PTX JIT compiler.
* Change dynamic loading of CUDA driver API functions to load 32-bit or 64-bit versions of depending on the the host architecture.
* Add ability to generate PTX kernels to be launched both on 32-bit and 64-bit hosts.
* Use Unified Virtual Memory APIs to perform array argument marshalling.
* PTX array storage test runs on the device and returns correct results.
* More integer test failures on GPU fixed.
