MERGE_VALUES nodes. Replacing the result values with the operands in one MERGE_VALUES node may cause another MERGE_VALUES node be CSE'd with the first one, and bring its uses along, so that the first one isn't dead, as this code expects. Fix this by iterating until the node is really dead. This fixes PR4699. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78619 91177308-0d34-0410-b5e6-96231b3b80d8
