[turbofan] Fix bug in Typer::TypeInductionVariablePhi The fix in b8b6075021ade0969c6b8de9459cd34163f7dbe1 was insufficient. The bug is that induction variable typing does not take into account that the value can become NaN through addition or subtraction of Infinities. The previous fix incorrectly assumed that this can only happen when the initial value of the loop variable is an Infinity.
