Tested using this command:
/ffmpeg -pix_fmt yuv420p -s 1920*1080 -i ArashRawYuv420.yuv \
-vcodec rawvideo -s 1920*1080 -pix_fmt rgb24 -f null /dev/null

The fps increase from 389 to 640 on Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz

e934194b6a libswscale/x86/yuv2rgb: Change inline assembly into nasm code
The original inline assembly and nasm code have the same fps when called by command.
NASM code almost has no impact on the perfromance.
