[SCEV] Generalize (C * A /u C) -> A fold to (C1 * A /u C2) -> C1/C2 * A. (#157159)
Generalize fold added in 74ec38fad0a1289
(https://github.com/llvm/llvm-project/pull/156730) to support multiplying and
dividing by different constants, given they are both powers-of-2 and C1 is a
multiple of C2, checked via logBase2.
