SPIR-V transpiler

[hadronized]

I implemented the first, naive (yet fully working) GLSL writer in less than 12 hours. I think it’s worth it to write a SPIR-V writer as well, and it shouldn’t take too much time.

It’s not my own priority right now (because I don’t use vulkan nor GL4.6 yet) but if someone provides me with a fully working patch, I’ll accept it for sure.

The branch spir-v contains an untested initial implementation against shaderc.

The idea is to first test with that backend. We will write the semantics analysis later as it will depend on other features before being implementable.
