[X86] In X86DAGToDAGISel::PreprocessISelDAG, make sure we don't access N after we delete it.
If we turn X86ISD::AND into ISD::AND, we delete N. But we were continuing onto the next block of code even though N no longer existed.
Just happened to notice it. I assume asan didn't notice it because we explicitly unpoison deleted nodes and give them a DELETE_NODE opcode.
