Now that templates instantiations are no longer emitted for all modules that
even blink at them they seem to break due to being linkonce (if compiled with
any optimization level > 0), so let's give them weak linkage instead.
The difference is that unreferenced linkonce symbols can be deleted, while
weak symbols need to be preserved.
