Fix test failure on aarch64:
./tests/checkasm/checkasm --test=h264pred 479612
The mismatch between neon and C functions can also be reproduced using
the following bitstream and command line.
wget https://streams.videolan.org/ffmpeg/incoming/intra8x8pred_10bit.264
./ffmpeg -cpuflags 0 -threads 1 -i intra8x8pred_10bit.264 -f
framemd5 -y md5_ref
./ffmpeg -threads 1 -i intra8x8pred_10bit.264 -f
framemd5 -y md5_neon
