2019-06-21Gather interop moments in a more generic mannerAdrian Kummerlaender
i.e. return unshifted moments in a implicitly ordered float4 array. Cell positions are reconstructed by a vertex shaded analogously to how it is done in compustream.

Yields another ~5-10 MLUPS in the simple D2Q9 example. Now averaging at ~840 MLUPS for D2Q9 and ~ 400 MLUPS for D3Q19 on a K2200.

2019-06-15Add support for generating a D3Q19 kernelAdrian Kummerlaender
Note how this basically required no changes besides generalizing cell indexing and adding the symbolic formulation of a D3Q19 BGK collision step. Increasing the neighborhood communication from 9 to 19 cells leads to a significant performance "regression": The 3D kernel yields ~ 360 MLUPS compared to the 2D version's ~ 820 MLUPS.
