Cycles: Change OptiX curve vertex data generation to use more compact representation

Diff is easier to parse now (with "Ignore whitespace" on). Available curve primitive types are tied to the OptiX ABI version currently. I suppose it would be possible to check whether it's…

WIP: Rework CUDA kernel build to use separate compilation

I've restored functionality that was missing initially (like being able to compile for older architectures, serial builds, ...). Depending on which CUDA toolkit is used with the CMake CUDA…

Cycles: Wrong Motion Blur With GPU Using Optix API

Drivers pre-r550 are likely unaffected, yes, I didn't verify this though.

Cycles: Wrong Motion Blur With GPU Using Optix API

This is a driver bug unfortunately, a fix is in the works. Will notify when an updated driver is released.
