When truncated vector stores were being custom lowered in VectorLegalizer::LegalizeOp(), the old (illegal) and new (legal) node pair was not being added to LegalizedNodes list. Instead of the legalized result being passed to VectorLegalizer::TranslateLegalizeResult(), the result was being passed back into VectorLegalizer::LegalizeOp(), which ended up adding a (new, new) pair to the list instead. This was causing an assertion failure when a custom lowered truncated vector store was the last instruction a basic block and the VectorLegalizer was unable to find it in the LegalizedNodes list when updating the DAG root. llvm-svn: 188953
