    [Ada] Remove explicit call to Make_Unchecked_Type_Conversion
    
    Respect a comment in sinfo.ads, which says: "Unchecked type conversion
    nodes should be created by calling Tbuild.Unchecked_Convert_To, rather
    than by directly calling Nmake.Make_Unchecked_Type_Conversion."
    
    No test appears to be affected by this change, so this is just a
    cleanup.
    
    gcc/ada/
    
            * exp_ch6.adb (Build_Static_Check_Helper_Call): Replace explicit
            call to Make_Unchecked_Type_Conversion with a call to
            Unchecked_Convert_To.
            * tbuild.adb (Unchecked_Convert_To): Fix whitespace.
