[LLVMdev] FoldingSetNodeID operations inefficiency
...00 operands by a different operand. After each
such operand replacement, this snippen of code is typically executed
(see SelectionDAG.cpp):
// Now that we have modified U, add it back to the CSE maps.
// If it already exists there, recursively merge the results together.
