It was presuming functions always have template_info, but that changed with my DECL_LOCAL_DECL_P changes. Fortunately DECL_LOCAL_DECL_P fns are never member fns, so we don't need to go fishing out a this pointer. Also I realized I'd misnamed local10.C, so renaming it local-fn3.C, and while there adding the effective-target lto that David E pointed out was missing.
