    i965/sbe: fix active components for SSO programs with over 16 inputs

    When we have up to 16 FS inputs, the SF unit will reorder our inputs
    to be consecutive, however, when we have more than 16 we need to
    to read our inputs from the URB exactly as they have been
    output from the previous stage. This means that for SSO we have to
    consider if we have URB padding due to unused input locations.

    Specifically, this affects gen9 active components programming, since
    for things to work in scenarios with over 16 inputs that have padded
    regions we need to ensure that we program active components for the
    padded regions too. If we don't do this the hardware won't read
    the URB properly for inputs located after padded regions.

    Found empirically.

    Fixes (these also require a patch in CTS):
