This is a bugfix for SelectNodeTo. In certain situations, we could be selecting a node and use a mix of getTargetNode() and SelectNodeTo. Because SelectNodeTo didn't check the CSE maps for a preexisting node and didn't insert its result into the CSE maps, we would sometimes miss a CSE opportunity. This is extremely rare, but worth fixing for completeness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24565 91177308-0d34-0410-b5e6-96231b3b80d8
