Dimitry Andric 2c4ebe03a0 Make it possible to use the debug versions of std::map and std::multimap
with clang, by removing two unneeded using declarations.  Otherwise, you
would get errors similar to:

/usr/include/c++/4.2/debug/map.h:77:20: error: dependent using declaration resolved to type without 'typename'
      using _Base::value_compare;
                   ^

N.B.: Take care when you actually use the debug versions of any
libstdc++ header.  They are more likely to contain problems, because
they are exercised far less often, and since the standard library
complexity guarantees don't always apply anymore, compile times can
drastically increase.
