    intel/fs: Skip registers faster when setting spill costs

    This might be slightly faster since we're doing one read rather than
    two before we decide to skip.  The more important reason, however, is
    because no_spill prevents us from re-spilling spill registers.  In the
    new world in which we don't re-calculate liveness every spill, we may
    not have valid liveness for spill registers so we shouldn't even look
    their live ranges up.
