This reverts commit 580454526b.
The recommitted version contains an extra check to not peel if the
latch exit is controlled by a pointer induction.
Original message:
Remove the restriction that the loop must be known to execute at least 2
iterations when peeling the last iteration. If we cannot prove at least
2 iterations are executed, a check and branch to skip the peeled loop is
inserted.
