    r5xx: Index inputs and temps.
    This is not the same as r3xx indexing. It only tries to protect inputs on
    the pixel stack from getting clobbered by temps or texs.
    
    Texs don't need special treatment since they read from special input regs
    and write to the same temp regs as ALU/FC instructions.
