Remove all "used" static functions *after* we have performed all of

the implicit template instantiations we need to perform. Otherwise, we
end up erroneously diagnosing static functions as used if they were
only used within an implicit template instantiation. Fixes a bunch of
spurious failures when building Clang with Clang.
