The problem here is that:
1. mark_used doesn't add inline functions to the deferred function list if
processing_template_decl. (I guess this is a compile-time optimization, so
that the deferred function list isn't full of stuff that's only used in
uninstantiated templates.)
2. Kriang's patch means that during template instantiation there's no
substitution required; we've already resolved A<int>::foo. So, we do no
lookup, and therefore, do not call mark_used again. But, we don't want to do
lookup again, so Kriang's patch is a good thing.
I think the optimization in (1) is unsafe -- for exactly this test case.
