InstrEmitter's virtual register handling assumes that clones are emitted after the cloned node. Make sure this assumption actually holds. Fixes a "Node emitted out of order - early" assertion on the testcase. This is probably a very rare case to actually hit in practice; even without the explicit edge, the scheduler will usually end up scheduling the nodes in the expected order due to other constraints.
