    PR rtl-optimization/48971
    * ira.c (setup_pressure_classes): Don't check register move cost
    for classes with one registers.  Don't add pressure class if there
    is a pressure class with the same available hard registers.
    Check contains_reg_of_mode.  Fix a typo in collecting
    temp_hard_regset.  Ignore hard registers not belonging to a class.
