    libstdc++: Restore call to test6642 in string_vector_iterators.cc test 
[PR104874]
    
    The test call was accidentally omitted in r16-2484-gdc49c0a46ec96e,
    a commit that refactored this test file. This patch adds it back.

            * testsuite/24_iterators/random_access/string_vector_iterators.cc:
            Call test6642.
