// The 'b' variants ask for the v-table second.
// The 'c' variants ask for the v-table third.
// We do a separate CHECK-LATE pass because the RTTI defintion gets
// changed after the fact, which causes reordering of the globals.
// These are not separated into namespaces because the way that Sema
// currently reports namespaces to IR-generation (i.e., en masse for
// the entire namespace at once) subverts the ordering that we're
// trying to test.
