vc4: Add support for fragment discards

Graphics / Mesa 3D Graphics Library / Mesa - Eric Anholt [anholt.net] - 22 August 2014 12:16 UTC

Fixes piglit glsl-fs-discard-01 and -03, and allows a lot of mesa demos to start running. glsl-fs-discard-02 has a problem where the first tile is not getting stored on the first render.
