Hi!

The reason is chroma deblocking which is using q4 without pushing it to stack. 
:/
Unfortunately I am in Geneve this week and don't have ARM linux board with me 
so it is not easy to test.

Mickael Raulet: maybe guys at INSA could run tests this week if I make a fix? 
Could you ask?

I also have SAO, qpel and epel NEON patches for latest FFmpeg. They pass 
fate-hevc on Jetson TK1, but should be iOS and clobber checked.

this breaks the neon clobber test see:
