No pass found for various GSL FFT and Statistics methods

This issue references the C code, Makefile, and `make debug` output in this gist: [https://gist.github.com/RasmitDevkota/18f910de41bb455a77a65700e1394bc6](https://gist.github.com/RasmitDevkota/18f910de41bb455a77a65700e1394bc6), which I am running with the command `make -f Makefile clean && make -f Makefile gsl_fft_demo && ./gsl_fft_demo`.

The code demonstrates a use of some of the GSL FFT and Statistics methods for taking Fourier transforms and subsequently finding peaks. When the autodifferentiation step is commented out, the program compiles and runs successfully, but including the autodifferentiation step results in `Enzyme: No ... pass found for ...` errors as seen in the below trace.
```bash
$ make -f Makefile clean && make -f Makefile gsl_fft_demo && ./gsl_fft_demo
rm -f gsl_fft_demo
rm -f *.o

The `make debug` output is quite long so I have attached it in the gist above, but it also ends with the same type of error.
