Add a code generator for PTX and a GPU target

[GoogleCodeExporter]

Describe the New Feature:

We can already create a kernel of PTX instructions.  However, we do not
currently have a way of launching it on a GPU.  We need the following new
features:

1) A new executable kernel class that launches a PTX kernel on a GPU device
using the CUDA driver level api.
2) Additions to the Executive class to support detection of NVIDIA GPUs,
translation to executable GPU kernels, and memory allocation and copies
into the GPU address space.
3) Unit tests to make sure that this functionality works.

Which milestone does the feature belong to?
0.9.0

Which branch does the new feature go in?
Trunk
