libstdc++: glibc mallinfo deprecated, use mallinfo2 when version => 
2.33

     glibc mallinfo is now deprecated resulting in make check-performance
     failure. When glibc => 2.33 prefer mallinfo2.

     libstdcxx-v3/ChangeLog:

             * testsuite/util/testsuite_performance.h 
(__gnu_test::MallocInfo): New.
             (__gnu_test::malloc_info): New, replace mallinfo on current 
platform
             supporting it and use mallinfo2 when glibc >= 2.33.

Tested under Linux x86_64.

Ok to commit ?
