This patch is preparatory for the amdgcn plugin.  The current
implementation was written for CUDA in which the device associated with
the queue is inferred by some hidden magic (which seems questionable to
me but then I don't fully understand it).  The GCN plugin needs to know
for which device the queue is intended, so this simply provides that
information to the queue constructor.

OK to commit?

Thanks
