haha, fixed that artifact too. Strange flickering line in the spectrum at -100 dB was caused by reading some samples out of region

Now at least we get a continuous output signal from shift_addfast_cc/NEON. And we get a good result if the shift_rate is 0! (Okay, we get a bad result for anything else...)
