Summary: This patch implements my promised optimization to reunites certain sexts from operands after we extract the constant offset. See the header comment of reuniteExts for its motivation. One key building block that enables this optimization is Bjarke's poison value analysis (D11212). That helps to prove "a +nsw b" can't overflow.
