Try to fix CUDA rCuFFTPlan problem.

[BoundaryValueProblems]

I just commented out the following section in Utils.jl

# TODO this is somewhat kludgy, not sure why cu was converting these back
function CUDA.cu(P::FFTW.rFFTWPlan)
    return plan_rfft(cu(zeros(real(eltype(P)), P.sz)), P.region)
end
CUDA.cu(P::CUFFT.rCuFFTPlan) = P

function CUDA.cu(P::FFTW.cFFTWPlan)
    return plan_fft(cu(zeros(eltype(P), P.sz)), P.region)
end
CUDA.cu(P::CUFFT.cCuFFTPlan) = P

and also updated the version number to v0.3.5. It successfully precompiled.
