    x86: immediate operands don't allow for vector operations
    
    Neither masking nor broadcast are possible here, and RC/SAE get dealt
    with elsewhere.
    
    This also fixes gas crashes (i.e. "Fatal error: unable to continue with
    assembly"), since the return path being removed failed to restore
    input_line_pointer from save_input_line_pointer.
