i965: Fix flat integral varyings.
Previously, the vertex and fragment shader back-ends assumed that all varyings were floats. In GLSL 1.30 this is no longer true--they can also be of integral types provided that they have an interpolation qualifier of "flat". This required two changes in each back-end: assigning the correct type to the register that holds the varying value during shader execution, and assigning the correct type to the register that ties the varying value to the rest of the graphics pipeline (the message register in the case of VS, and the payload register in the case of FS). Fixes piglit tests fs-int-interpolation and fs-uint-interpolation. Acked-by: Kenneth Graunke <[email protected]>
