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
