The idea was that we could skip uploading the constant-indexed uniform data and just upload the uniforms that are variably-indexed. However, since the VS bin and render shaders may have a different set of uniforms used, this meant that we had to upload the UBO for each of them. The first case is generally a fairly small impact (usually the uniform array is the most space, other than a couple of FSes in shader-db), while the second is a larger impact: 3DMMES2 was uploading 38k/frame of uniforms instead of 18k. Given that the optimization is of dubious value, has a big downside, and is quite a bit of code, just drop it. No change in shader-db. No change on 3DMMES2 (n=15).
