  Log Message:
  -----------
  Move to before consecutive memops widening, and only propagate MV'ed constant without widening

  Log Message:
  -----------
  Revert adding `widenUnitStridedLoadStore` helper

We now rely on the actual consequtive memops widening in a single place (both
original and speculated/mv'ed).
