[Bug libstdc++/21193] New: provide better std::tr1::hash for std::string and std::wstring

[TazForEver at dlfp dot org]

The current implementation of std::tr1::hash for std::string and std::wstring is
pretty bad. I think FNV should be used instead.

I'm attaching a patch that may not be optimal when size_t is 64bits.
