/* Returns the decl for a function which will return a type_info node for
TYPE. This version does not mark the function used, for use in
set_rtti_entry; for the vtable case, we'll get marked in
finish_vtable_vardecl, when we know that we want to be emitted.
We do this to avoid emitting the tinfo node itself, since we don't
currently support DECL_DEFER_OUTPUT for variables. Also, we don't
associate constant pools with their functions properly, so we would
emit string constants and such even though we don't emit the actual
function. When those bugs are fixed, this function should go away. */
