[REQUEST]: Support Nvidia's cuFFTDx library

[eschnett]

Is your feature request related to a problem? Please describe

It would be convenient if the cuFFTDx library https://docs.nvidia.com/cuda/cufftdx/index.html was available on the compiler explorer.

Describe the solution you'd like

I would like to be able to use #include <cufftdx.hpp> to study how the PTX and SASS code that is generated for the cuFFTDx kernels looks like.

Describe alternatives you've considered

The alternative is to install cuFFTDx on a system with an Nvidia GPU and compiler and examine the code there.
