    libstdc++: Fix access error in __gnu_test::uneq_allocator
    
    The operator== function is only a friend of the LHS argument, so cannot
    access the private member of the RHS argument. Use the public accessor
    instead.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/util/testsuite_allocator.h (uneq_allocator): Fix
            equality operator for heterogeneous comparisons.
    
    (cherry picked from commit 0585daf7de0673ade9feca1be66a68178786b48d)
