Revert r152613 (and r152614), "Inline the d'tor and add an anchor instead." for workaround of g++-4.4's miscompilation. 

It caused MSP430DAGToDAGISel::SelectIndexedBinOp() to be miscompiled.
When two ReplaceUses()'s are expanded as inline, vtable in base class is stored to latter (ISelUpdater)ISU.
