gallium: introduce GLSL based interpolation rules. (v2)
This introduces an unspecified interpolation paramter that is only allowed for color semantics, so a specified GLSL interpolation will override the ShadeModel specified interpolation, but not vice-versa. This fixes a lot of the interpolation tests in piglit. v2: rename from unspecified to color Signed-off-by: Dave Airlie <[email protected]>
