Krzysztof Pyrkosz 9fb97215df avcodec/aarch64/opusdsp_neon: Simplify opus_postfilter_neon 
This change removes one extra floating point operation and simplifies
load operations at the beginning of the loop by using dedicated register
for each of the 5 pointers and interleaving it with calculations. The
first case seems to be a bit slower, but the performance increase is
substantial in the other two.
