    A llvm/test/CodeGen/X86/pr49466.ll

  Log Message:
  -----------
  Restore fixed version of "[CodeGenPrepare] Fix isIVIncrement (PR49466)"

Change was reverted in commit 8d20f2c2c66eb486ff23cc3d55a53bd840b36971 because it was causing an infinite loop.  9228f2f32 fixed the root issue in the code structure, this change just reapplies the original change w/adaptation to the new code structure.
