Marshall, Eric, Hans,
Any objections to backporting this to 5.0? It fixes a potential visibility
issue for clients of the header.

Log:
[libc++] Hoist extern template above first use
This function template is referenced inside class basic_string as a
friend function. The extern template declaration needs to be above that
friend declaration to actually take effect.
This is important because this function was marked as exported in
r307966, so without the extern template taking effect, it can leak into
other DSOs as a visible symbol.
