In addition to the actual vertex coordinates blorp will get another vertex input buffer providing the constants that are until now provided as uniforms. This will remove the need to configure push constants and their allocation in the pipeline.
First three patches refactor the vertex data setup for blorp. The existing logic in blorp already supports all gens (gen6-gen9). I chose to change the core upload logic accordingly and simply use that for blorp. Patches 5-8 pack the constants in blorp programs into vec4s. By default compiler puts input variables two full hardware registers apart. Having them in vec4s drops the need to repack them. Last four patches take actual advantage of the change by dropping unnecessary pipeline reconfiguration.
