nir: Implement a Mesa IR -> NIR translator.
Shamelessly ripped off from Eric Anholt's tgsi_to_nir pass.
This is not built on SCons, like the rest of NIR.
v2:
- Delete redundant c->s, c->impl, and c->cf_node_list pointers (Ken)
- Use nir_builder directly instead of ptn_compile in more places (Ken)
- Drop 'struct' keyword in front of nir_builder (ken)
- Add a file level Doxygen comment (Ken)
- Use scalar constants instead of splatting (Eric)
- Use nir_builder helpers for constants, moves, and swizzles (Connor)
v3: Minor indentation improvements.
