consider removing device-to-device copy workaround for absence of nvcc #449

Closed GoogleCodeExporter closed 8 years ago

IIRC we decided to eliminate this WAR because it violates the one-definition 
rule and there's no way to ensure we get the "good" version when both are 
present.

I'll take a look at this later.  I can't say what the right approach is, but 
I'm concerned about the silent (and hard to diagnose) performance hazard that 
this introduces.
