opencl_fft1d_x64_linux_14 fft algorithm is broken

The FFT algorithm in the opencl 1d fft sample isn't implemented correctly. In the example, the program generated random numbers for the fft input. It is then computed by the fft1d kernel, and checked...

Then, when opencl_fft1d_x64_linux_14 fft algorithm can be fixed in order, NOT like this in bit reversed order? I hope it could be upgraded with ordered result.

Also, I need radix 2 FFT algorithm, can compute 512 FFT or 2048 FFT, even though radix 2 FFT algorithm do much more multiplication and less addition than radix 4 FFT in FPGA board.
