Fix a bug in which a node could be added to the worklist twice: UpdateNodeOperands could morph a new node into a node already on the worklist. We would then recalculate the NodeId for this existing node and add it to the worklist. The testcase is ARM/cse-libcalls.ll, the problem showing up once UpdateNodeOperands is taught to do CSE for calls. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58246 91177308-0d34-0410-b5e6-96231b3b80d8
