[Mesa-dev] [PATCH 1/3] nir: Add a lowering pass for gl_FragColor to glFragData[] writes.

For VC5, the shader needs to have the appropriate base type for the variable in the render target write, and gallium's FS_COLOR0_WRITES_ALL_CBUFS (used for glClearBufferiv) doesn't give you that information. This pass lets the backend decide what types to explode the gl_FragColor write out to.
