avcodec/aarch64/aacencdsp: NEON implementation
This patch supplies handwritten NEON code for AAC.
The benchmarks below were collected by invoking these two commands on
each of my boards, A78, A72 and Thinkpad x13s:
1) ./tests/checkasm/checkasm --test=aacencdsp --bench --runs=12
2) ./ffmpeg -y -t 10:00 -f lavfi -i sine /tmp/foo.aac (the first line is
speed without the patch, second, with)
