    M llvm/test/Transforms/LoopFlatten/loop-flatten-gep.ll

  Log Message:
  -----------
  [Transforms] Preserve inbounds attribute of transformed GEPs when flattening loops (#86961)

When flattening the loop, if the GEP was inbound, it should stay
inbound, because the only thing that changed is how the pointers are
calculated, not the elements being accessed.
