[committed] libstdc++: Remove dependency from std::bitset::to_ulong() test

[Jonathan Wakely via Gcc-patches]

Tested x86_64-linux. Pushed to trunk.

-- >8 --

There's no need to use a stringstream to test the to_ulong() member.
This will allow the test to be used in freestanding mode.

libstdc++-v3/ChangeLog:

        * testsuite/20_util/bitset/access/to_ulong.cc: Construct bitset
        from binary literal instead of using stringstream.
