That particular library isn't currently suitable for Vulkan, it is based on the
OpenCL SPIR-V dialect, which is somewhat different than the Vulkan SPIR-V
dialect. Additionally, it is based on a really old version of LLVM last I
checked.

If you're going to base everything on Mesa, you should use the NIR code, since
there is already a Vulkan SPIR-V to NIR translator. You would need to write the
NIR to vectorized LLVM translator.
