  Log Message:
  -----------
  [LoopIdiom] Update strlen idiom body loop condition to be clean up by LoopDeletion (#134906)

Fixes the case where subsequent passes were unable to find and delete
the invariant loop left over by the strlen idiom conversion. Since
`loop-deletion` only operate on computable loops, we can update the loop
condition to something more easily picked up by `loop-deletion`

As pointed out in https://github.com/llvm/llvm-project/issues/134736
