Huho!

Cons:
    - it's c++
    - only GFX8 and GFX9 (I have GFX6 :( )
    - some nasty python scripts (there are tons in mesa)

Pros:
    - it's several orders of magnitude less brain f*cked than llvm.
    - it is actual working code which does disjoint mesa from llvm.

conclusion:
    - for GFX8 and GFX9, it's less worse than llvm.
    - I was asking for a clean GCN ABI definition document from shaders
      perspective, maybe this code will help to write one (or it is an AMD
      confidential document??).
