SPIR-V tools did not turn out to be useful, but increased the
binary size by a significant amount and caused build problems.
- spirv-opt: Far too slow for the intended purpose, and Nvidia
specific shader issues have been reported and fixed.
- spirv-val: Not much value in practice since shaders can be
written to a directory and validated manually.
