[SLP] Make getSameOpcode support interchangeable instructions. (#135797) ...

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.
