dev-libs/intel-neo: new package

New OpenCL driver for Broadwell and newer. For older systems stick with
dev-libs/beignet.

Tested on Kaby Lake and Kaby Lake R, in both cases LuxMark manages to
render all three scenes without errors or crashes.

No multilib support yet because running a 32-bit build on amd64 causes
type conflicts, will look at it later.
