[M144 Merge] [maglev] fix CanElideWriteBarrier Smi recording for phis

Recording a Tagged use is not enough for 2 reasons:

• Tagged uses are sometimes ignored, in particular for loop phis
  where we distinguish in-loop and out-of-loop uses.

• This Tagged use could only prevent untagging of this specific phi,
  but none of its inputs. So we could have a Smi phi as input to the
  current phi which gets untagged and retagged to a non-Smi, all
  while the current phi doesn't get untagged.
