    [Ada] Remove redundant guard in checks for volatile actuals
    
    When flagging names of volatile objects occurring in actual parameters
    we guard against identifiers without entity. This is redundant, because
    earlier in the resolution of actual parameters we already guard against
    actuals with Any_Type.
    
    Code cleanup related to handling of volatile components; behaviour is
    unaffected.
    
    gcc/ada/
    
            * sem_res.adb (Flag_Effectively_Volatile_Objects): Remove
            redundant guard.
