* Represent uniform facts via descriptor set and binding. Previously uniform facts were expressed with resepect to the id of a uniform variable. Describing them with respect to a descriptor set and binding is more convenient from the point of view of expressing facts about a shader without requiring analysis of its SPIR-V. * Fix equality testing for uniform buffer element descriptors. The equality test now checks that the lengths of the index vectors match. Added a test that exposes the previous omission.
