vpupdates was merged into v18 5 minutes ago. Starting from the next nightly build you will therefore be able to use HEVC-10 bit decoding on VAAPI.

Remember: Mesa 17.1 or later and libva/ libva-driver-intel 1.7.3 or later ist needed.

For Ubuntu 16.04 and 17.04 there is a mesa stable ppa:

sudo add-apt-repository ppa:paulo-miguel-dias/pkppa
sudo apt-get update
sudo apt-get dist-upgrade

Edit: Don't update for now, please. A patch was forgotten and now VAAPI will be skipped - carefully watch github for changes.
