  Log Message:
  -----------
  [LV] Remove redundant parameter in IV live-out optimization (#195036)

When optimizing induction variable live-out values, passing PredVPBB is
no longer necessary as the VPBasicBlock can be retrieved from the
incoming value of exit phis.

This patch ensures the escapee of induction variable is inserted before
the recipe that defines the incoming value, and removes the redundant
PredVPBB parameter passing.
