In Direct3D, a stream-output geometry shader can be created from a
vertex shader bytecode. We generate a pass-through geometry shader in
this case. Pass-through geometry shaders are helpful because they can
easily split outputs when rasterization is disabed. We could also add
another codepath in order to avoid geometry shaders when possible.
