Add some missing forward declarations.

These are functions for which explicit specializations exist in the .cc file. The
standard says that we need to forward-declare them. In practice, it doesn't matter,
but it did matter for an experiment I'm currently running that explicitly makes use
of the fact that these functions are specialized.
