    libstdc++: Make dg-error pattern more accurate
    
    Remove useless test variable and use a more accurate dg-error pattern so
    that only the ill-formed expression compilation error is considered.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/23_containers/map/operators/1_neg.cc (test01): Remove 
test variable
            and use 'no match' dg-error patter.
            * testsuite/23_containers/set/operators/1_neg.cc (test01): Likewise.
