Revert "[SCEV] Fold (C1 * A /u C2) -> A /u (C2 /u C1), if C2 > C1." (#158328) Reverts llvm/llvm-project#157656 There are multiple reports that this is causing miscompiles in the MSan test suite after bootstrapping and that this is causing miscompiles in rustc. Let's revert for now, and work to capture a reproducer next week.
