Add missing explicit instantiation for std::lower_bound template

Since commit r195676[1], it looks like
libstdc++-v3/src/c++11/hashtable_c++0x.cc is missing an explicit
instantiation for std::lower_bound.  This leads to libstdc++.so having
the symbol for that (missing) instantiation be undefined, thus
preventing executables from being linked with libstdc++.

The patchlet below seems to fixed the issue for me.

Boostrapped and tested on x86_64-unknown-linux-gnu.
