Bug#838908: src:arrayfire: New upstream release (3.4.0)

[Ghislain Antony Vaillant]

Package: src:arrayfire
Severity: wishlist
Control: block -1 by 837112

ArrayFire version 3.4.0 has been released. The goal would be to have this
version released with Stretch.

This issue is currently blocked by the missing opencl-clhpp package. It
would (optionally) require the `forge` source package to be sponsored
too, in order to enable the graphics functionality of ArrayFire.
