71a0cfd9 - [SLP] Make getSameOpcode support interchangeable instructions. (#127450)

[SLP] Make getSameOpcode support interchangeable instructions. (#127450) We use the term "interchangeable instructions" to refer to different operators that have the same meaning (e.g., `add x, 0` is equivalent to `mul x, 1`). Non-constant values are not supported, as they may incur high costs with little benefit. --------- Co-authored-by: Alexey Bataev <a.bataev@gmx.com>
