    [Ada] Improve building of untagged equality
    
    When checking components of a record type for their own user-defined
    equality function it is enough to find just one such a component.
    
    Cleanup related to handling of user-defined equality in GNATprove.
    
    gcc/ada/
    
            * exp_ch3.adb (Build_Untagged_Equality): Exit early when the
            outcome of a loop is already known.
