wined3d: Reload the first 8 constants on a 1.x and != 1.x ps switch.
ps 1.x constants are clamped to [-1;1], constants in >= 2.0 pshaders are not. This means we have to reload constants when switching between those shader types in ARB. In GLSL this is not a concern because constants are tied to program objects and are reloaded on a shader change anyway.
