nir: Implement a Mesa IR -> NIR translator

Graphics / Mesa 3D Graphics Library / Mesa - Kenneth Graunke [whitecape.org] - 27 March 2015 23:16 UTC

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.
