CI looks "good" (Travis is green). Any objections? If not, I'd like to merge this so that we can have CI for some new and fancy features over at CUDAnative.jl (JuliaGPU/CUDAnative.jl#362). |

This is useful for calling into libraries that are linked by CUDAnative, both libraries with PTX bitcode (
libdevice, like here) and libraries with PTX assembly (libcudadevrt). We currently do this with a nasty macro that generatesllvmcallexpressions that declare the function, but that duplicates functionality from theccallimplementation in Julia.
