Reland [VPlan] Simplify pow-of-2 (mul|udiv) -> (shl|lshr) (#174581) ...

The original patch, landed as a2db31b0 ([VPlan] Simplify pow-of-2
(mul|udiv) -> (shl|lshr), #172477) had a critical commutative matcher
bug, which has now been fixed. An assert has also been strengthened,
following a post-commit review.
