This series lives on my gles3-glsl-packing branch.
Tested against my piglit gles3-glsl-packing branch on gen6 and gen7. All tests
pass. However, the tests and implementation share much common code and
concepts, so thorough review is welcome.
This is my first attempt at emitting native i965 code, so please review it
carefully. Just because it passes my tests does not imply that it's correct.
In patch "i965/vs/gen7", there is a comment explaining a potential
optimization that I did not know how to achieve. I'm happy committing this
series as-is without the optimization, but I'd like feedbach on how to achieve
it so I can do it in a follow-on series.
