What version of PTX should we generate? #5

Right now the nvptx targets generate PTX 3.2 but we can generate PTX with newer versions -- up to 4.2 -- using the features field of the target specification.

I would definitely default to newer versions, unless there is a specific issue with the newer versions(e.g. backwards compatability).
