Just as an FYI, this is what we are actually using together with a few WIP branches in Mesa. Of note is that we run the LLVM StructurizeCFG pass before generating SPIR-V, else vtn chokes on it, even with the WIP Mesa structuriser.


Add a target to emit SPIR-V targeted to Mesa's DXIL backend, using
32-bit SPIR-V 1.0.

Substantially based on Dave Airlie's earlier work.
